This is done by plotting the values of each variable on a different axis, such as the value of marketing expenditure on the horizontal axis (the x-axis or independent axis), and the value of sale revenue on the vertical axis (y-axis or dependency axis).</p><p><span style="font-family:arial,helvetica,sans-serif;">In theory, the more money a person earns, the more they spend per time period. Market research can be used to determine the extent to which there is a strong correlation between income and expenditure levels. In the scatter diagram below, each dot represents a respondent, with their income shown along the x-axis and their expenditure plotted on the y-axis, per time period.</span></p><p><span style="font-family:arial,helvetica,sans-serif;"><img alt="" height="294" src="../../../ib/businessmanagement/images/4.4-scatter-diagram.jpg" width="500"></span></p><p>The graph can then help to determine the degree to which one variable impacts the other.

This means the relationship between the two variables is inconclusive or unrelated, such as the demand for coffee and the price of umbrellas.</p></li></ul><p>The main advantage of using scatter diagrams is that they can show patterns and therefore correlations in a visual way. The main limitation, however, is that the tool does not reveal causation (the reason or reasons behind the relationship between the two variables under investigation).</p></div></div><div class="panel-footer"><div></div></div></div><div class="panel panel-purple panel-expandable"><div class="panel-heading"><a class="expander pull-right" href="#"><span class="fa fa-plus"></span></a><div><p><strong><span style="font-family:arial,helvetica,sans-serif;">Line of best fit</span></strong></p></div></div><div class="panel-body"><div><p><img alt="" height="191" src="../../../ib/businessmanagement/images/toolkit-(bmt)/regression---line-of-best-fit.jpeg" width="290"></p><p>A<strong> line of best fit </strong>is a statistical technique used to show the relationship or correlation between variables on a scatter diagram. The line of best fit (also known as the <strong>regression </strong><strong>line</strong>) is drawn through the different data points plotted on a scatter graph that evens out variations in the data set.</p><p>The line of best fit is used to identify any underlying patterns or relationship between the variables being investigated.

Any readings or interpretations from the line of best fit will be estimations.</p><section class="tib-teacher-only" readonly="true" title="This box is not visible to students"><div class="header" readonly="true"><img class="icon" src="../../../thinkib/icons/teacher-only.svg"> Teacher only box</div><div class="content" readonly="false"><p><em><span style="color:#FF0000;">Note to teachers:</span></em></p><p><span style="color:#FF0000;">For IB assessment purposes, HL students will <u>not</u> be expected to calculate the line of best fit. Although the line of best fit can be derived by using a statistical equation, only an approximation is required. You can do this by looking at the data and drawing a straight line that seems to best show the relationship between the data in the scatter graph.</span></p><p><span style="color:#FF0000;">For reference only, the equation to find the line of best fit is:</span></p><p style="text-align: center;"><span style="color:#FF0000;">Y` = bX + A</span></p><p><span style="color:#FF0000;">where,</span></p><ul><li><p><span style="color:#FF0000;">Y` denotes the predicted value</span></p></li><li><p><span style="color:#FF0000;">denotes the slope of the line</span></p></li><li><p><span style="color:#FF0000;">X denotes the independent variable, and</span></p></li><li><p><span style="color:#FF0000;">A is the y-axis intercept.</span></p></li></ul><p><span style="color:#FF0000;">Once the scatter points are plotted on a diagram, draw a straight line that passes through as many data points as possible. The line should be as close as possible to all points. For points not on the line of best fit, there should be approximately half the data point above the line, and half below the line.</span></p></div></section><div class="yellowBg"><h6><span style="color:#FF0000;"><span style="font-family:arial,helvetica,sans-serif;"><span class="snippet-fa fa fa-lightbulb-o fa-lg" style="color: rgb(103, 7, 124);"> </span> Top tip!</span></span></h6><p>A key limitation of a correlation shown by a line of best fit is believing there is a causal link between the two variables under investigation, when, in fact, they are not actually related.

It is a statistical process of establishing a relationship (or connection) between two or more variables. For example, research from the <a href="https://hongkongfp.com/2023/07/10/over-30-of-hong-kong-students-have-binge-gamed-as-experts-warn-of-mental-health-issues-linked-to-online-addiction/">Chinese University of Hong Kong's medical faculty</a> has found that Internet gaming disorders and mental health problems are significantly correlated. In the world of business, correlation is widely used in financial analyses and to support strategic decision making.</p><p>Examples of correlation, which can be determined by using simple regression tools, may include:</p><ul class="branded"><li><p>As the weather gets warmer, the demand for ice cream increases.</p></li><li><p>The more it rains, the higher the demand for umbrellas.</p></li><li><p>The more people visit the cinema or movie theatre, the greater the spending on popcorn.</p></li><li><p>The less a firm spends of marketing, the fewer the number of customers it will have.</p></li><li><p>Spending more on research and development (R&D) leads to more innovation.</p></li><li><p>The longer a member of staff works at an organization, the higher their chances are of being promoted to a higher rank.</p></li><li><p>The greater the spending on staff training the development, the more productive workers become.</p></li><li><p>An increase in average incomes tends to lead to a higher level of consumer expenditure.</p></li></ul><p><strong>Extrapolation </strong>is a statistical forecasting technique that makes future predictions of sales (in units or dollars) based on trends identified from using past data. It works by using<span style="font-family:arial,helvetica,sans-serif;"> a line of best fit (for a particular data set) and extending this line to make predictions, such as future sales revenue.</span></p><p><span style="font-family:arial,helvetica,sans-serif;"><img alt="" height="240" src="../../../ib/businessmanagement/images/4.3-3.jpg" width="460"></span></p><p><span style="color:#696969;"><em><span style="font-family:arial,helvetica,sans-serif;">Example of extrapolation of sales data</span></em></span></p><p>Note that extrapolation is only effective if the relationship between the dependent and independent variables is linear (i.e. a clear line of best fit can be established).</p><p>Other examples of how managers might use simple linear regression to support problem solving and decision making include:</p><ul class="branded"><li><p>Analyzing survey data to understand indicators such as the degree of customer satisfaction and product preferences (see <a href="../44679/44-market-research.html" title="New syllabus (first teaching 2022) » Unit 4 - Marketing » 4.4 Market research">market research</a>).</p></li><li><p>Assessing business risks to support decision making (see <a href="../45242/57-crisis-management-contingency-planning-hl.html" title="New syllabus (first teaching 2022) » Unit 5 - Operations Management » 5.7 Crisis management & contingency planning (HL)">contingency planning and crisis management</a>).</p></li><li><p>Building linear regression models for machine learning to support problem solving (see <a href="../45858/artificial-intelligence.html" title="New syllabus (first teaching 2022) » Unit 5 - Operations Management » 5.9 Management Information Systems (HL) » Artificial intelligence">artificial intelligence</a>).</p></li><li><p>Making sales estimates at different times of the year (see <a href="../44660/43-sales-forecasting-hl.html" title="New syllabus (first teaching 2022) » Unit 4 - Marketing » 4.3 Sales forecasting (HL)">sales forecasting</a>).</p></li><li><p>Predicting how changes in price is likely to impact consumer behaviour (see <a href="../42547/452-price-1.html" title="New syllabus (first teaching 2022) » Unit 4 - Marketing » 4.5 The seven Ps of the marketing mix » 4.5.2 Price">price elasticity of demand</a>).</p></li></ul><div class="yellowBg"><h5><span style="font-family:arial,helvetica,sans-serif;"><span class="snippet-fa fa fa-file-text-o fa-lg" style="color: rgb(61, 30, 128);"> </span> <span style="color:#FF0000;">Case Study 1 - The Price of Starbucks Coffee</span></span></h5><p>The range of prices of a Tall Latte from Starbucks in different parts of the world is quite remarkable.

They are often used by business analysts to make forecasts of future outcomes.</p></li><li><p>Enhances decision making - Managers and entrepreneurs rely on quantitative data and financial analyses to aid strategic decision making. Simple linear regression techniques enable such analyses to have greater levels of accuracy and trustworthiness, thereby supporting businesses in testing various hypotheses and developing more appropriate strategies.</p></li><li><p>Reveals new business opportunities - Simple linear regression analysis, such as correlation, can help to reveal new business opportunities that might not have otherwise been available or may have gone unnoticed by decision makers as the information was unavailable. Instead, the tools enable decision makers to gain insights into new business opportunities that can be put to strategic use.</p></li><li><p>Reduces errors and risk associated with business strategy - Simple linear regression techniques enable business people to test theories, strategies, and hypotheses in order to determine if they are likely to be feasible and successful. Gaining access to the right data helps to have fewer errors, and so reduces risks. As a quantitative BMT, simple linear regression is based on evidence to support decision making, rather than decision makers relying purely on past experiences and/or their own intuition.</p></li><li><p>Improved management - Overall, simple linear regression techniques help managers and entrepreneurs to manage their businesses more efficiently, such as resource allocation, employee productivity, and budgeting.</p></li></ul><hr class="hidden"><h5><span style="font-family:arial,helvetica,sans-serif;"><span class="snippet-fa fa fa-times-circle-o fa-lg" style="color: rgb(61, 30, 128);"> </span> Limitations of simple linear regression</span></h5><p>The potential limitations of using simple linear regression include:</p><ul class="branded"><li><p><span style="font-family:arial,helvetica,sans-serif;">Cause versus effect - Being able to establish a correlation between two or more variables does not necessarily enable managers to determine the causes of the relationship or connections. For example, there are numerous factors that can cause an increase in the demand for a firm's goods or services, despite its advertising expenditure. Linear regression does not necessarily enable managers to know how a change in one variable causes a change in another variable. See Box 1 for some real-world examples.</span></p></li><li><p>Such statistical techniques can be both time consuming and expensive to conduct. A large and representative data set is required to generate meaningful results.</p></li><li><p>Linear regression is sensitive to outliers. Outliers of a data set refer to anomalies, irregularities, and extreme values that deviate from the other data points. Outliers can drastically change a line of best fit and any corresponding correlation may have a low degree of accuracy.</p></li><li><p>The past is not indicative of the future - Just because a correlation might be established from a data set does not mean that the trend will continue into the future. For example, the outbreak of the COVID-19 pandemic - which no one could have predicted - caused major havoc to all industries across the world. The chart below shows a positive sales revenue trend for cinemas in the UK, although the coronavirus outbreak soon put an end to that.</p></li></ul><p><span style="font-family:arial,helvetica,sans-serif;"><img alt="" src="../../../ib/businessmanagement/images/bmt/cinema-revenue-uk.jpg" style="width: 640px; height: 388px;"></span></p><p><span style="color:#696969;"><em>The COVID-19 pandemic was a major threat to the survival of cinemas in the UK and elsewhere</em></span></p><div class="yellowBg"><h5><span style="color:#FF0000;"><span style="font-family:arial,helvetica,sans-serif;">Box 1 - Cause versus Effect</span></span></h5><p>Tyler Vigen, a former student at Harvard University, shared the following examples on his <a href="http://www.tylervigen.com/spurious-correlations">website</a> as a reminder to us to look carefully at statistics.</p><p><img alt="" src="../../../ib/businessmanagement/images/bmt/correlation.jpg" style="width: 400px; height: 250px;"></p><ul class="branded"><li><p>Margarine consumption has a 99.26% correlation with divorce rates in Maine, US.</p></li><li><p>Total revenue generated by arcades has a 98.51% correlation with Computer Science doctorates awarded in the US.</p></li><li><p>Worldwide non-commercial space launches has a 78.92% correlation with Sociology doctorates awarded in the US.</p></li><li><p>The consumption of mozzarella cheese has a 95.82% correlation with Civil Engineering doctorates awarded in the US.</p></li><li><p>The per capita consumption of chicken has a 89.99% correlation with total US crude oil imports.</p></li></ul></div><div class="yellowBg"><h5><span style="color:#FF0000;"><span style="font-family:arial,helvetica,sans-serif;"><span class="snippet-fa fa fa-lightbulb-o fa-lg" style="color: rgb(103, 7, 124);"> </span> Top tip!</span></span></h5><p>Establishing correlation through simple linear regression does not mean a business will always benefit from the results.
