As time spent running increases, body fat decreases. In other words, the variable running time and the variable body fat have a negative correlation. This term is defined in the 5th edition of the PMBOK. A scatter plot matrix shows all pairwise scatter plots for many variables. The more time an individual spends running, the lower their body fat tends to be. For example, a simple scatterplot could be used to determine if there is a linear relationship between lawyers salaries and the number of years they have. The former lets project managers analyze relationships between two variables but the latter helps determine the effect of a specific root cause. The scatter diagram is entirely different from another basic quality tool called the fishbone diagram. Many people confuse scatter diagram with the fishbone diagram. A scatter plot can be defined as a graph containing bivariate data in the form of plotted points, which allows viewers to see a correlation between plotted. You can find a correlation when a cause-and-effect link exists between both variables. You can use a regression line to predict how a change in one variable will likely affect the value of a dependent variable. If this particular project management quality tool can establish a relationship between two variables, a regression line can be calculated to estimate how the change of the independent variable will affect the value of the other variable. A correlation in a scatter diagram occurs when two variables are determined to have a connection. Establishing a correlation to understand how the dependent variable can strongly influence the dependent variable is used to make better decisions for the project. The direction of the correlation may be proportional (positive relationship), inverse (negative relationship) or may not exist at all (zero correlation). A scatterplot depicting the temperature in January across latitudes. Scatter diagrams are correlation charts that utilize regression lines to predict how the change in the independent variables (X) will change the dependent variables (Y). Scatter plots are described as linear or nonlinear. If we see the correlation between the student’s height and arm length exhibit a trend, we can estimate the arm length of a student with a certain value of height given and vice-versa. These tools are important for planning, monitoring and controlling different issues related to the quality within the organization. Scatter graphs Scatter graphs are a good way of displaying two sets of data to see if there is a correlation, or connection. Scatter Chart Example: Arm Length on Grade 11 The scatter graph shows information about the height and the arm length of each of 8 students in Year 11. There are seven basic project management tools used in project management and one of these seven tools is the scatter diagram. ![]()
