In this module, we will cover Box Plots. Box plots are a graphical representation of data that helps the users quickly gather summary information of the data - for example, get an idea of the minimum value, maximum values, and the central location of the data (median). We would typically use a Box Plot for continuous data and usually to compare multiple groups.

About this course
In this module, we will cover Contour and Surface Plots. If we have a single variable function, such as Y = f(X) then we can use an XY plot to understand the variation between X and Y. However, if we have a function of two variables such as Z = f(X, Y), we can use a contour or surface plot to understand the relationship between X, Y, and Z.
Typically, for contour plots, X, Y, and Z are continuous variables. Contour plots can be used to visually understand what values of X and Y result in a given value of Z or to minimize or maximize the Z values for optimization problems.

Typically, a 95% confidence interval is used but any other confidence level can be specified as well.

In this module, we will cover Multi-Vari Charts. A multi-vari chart is a graphical chart that visually shows where the major variation in the data set is coming from. It is called a multi-vari chart because usually multiple variables are plotted on the same chart. Variations in data can come from multiple sources. On a multi-vari chart, the source of variation is typically represented as variation within a part/product, variation in the short term, and variation in the long term.

In this module, we will cover Probability Plots. The probability plot is a graphical method of determining if the data follows a given distribution. The given data is plotted on a probability plot, a Q-Q plot, or a P-P plot to determine if the data follows a given distribution. For example, if the Q-Q plot shows that the data follows a 45-degree line, we can conclude that the data follows that distribution.

About this course
In this module, we will cover Scatter Plots. A scatter plot is used to visually determine if there is any relationship between two variables (say X and Y). This plot is usually used between two continuous variables. However, a scatter plot can also be drawn if the variables are not truly continuous – for example, the variable may be discrete ordinal data but more than 2 categories. A scatter plot is a visual way of looking for relationships and thus may be subjective. If a more objective way of establishing a relationship is required then we can use some statistical tool like Regression analysis.

About this course
In this module, we will cover Time Series Plots. A time series plot is a graph that displays data collected in a time sequence from any process. The chart can be used to determine how the data is trending over time and if the data points are random or exhibit any pattern. For example, you may want to determine whether the number of calls received in a call center is consistent month over month or if there is any specific pattern in the data – such as a decreasing trend, or an increasing trend. You can also use a times series plot to determine if a process is stable by visually looking for clues about stability.

About this course
The normal distribution also known as the Gaussian distribution or the bell curve is a very common distribution and the data collected from a number of processes follow this distribution. Knowing that a distribution is normal can help us make useful predictions about the process. Graphically, we can use the histogram to determine if the data is normally distributed however, this could be subjective. In this module, we will look at how we can use some statistical tests to determine normality.

About this course
The objective of the catapult is to launch a projectile that can hit the enemy located at a specific distance - hence the primary metric for this device is to achieve a given distance with minimum variation. A scale-model catapult has become a useful tool for simulating process variation and the impact of process variables on process output. There are 8 variables you can control on the catapult plus 2 operator settings to influence the outcome. The output from this exercise is the distance of the point of impact of the ball from the front of the catapult. Some of the 10 variables may have little or no impact, some variables may have a medium impact and some may have a large impact on the distance achieved.
This simulation can be used as either an individual or a team exercise to learn the various statistical concepts covered in a typical Lean Six Sigma training class. You can use the catapult to collect data and analyze the data to understand concepts such as measurement systems analysis, capability analysis, control charts, hypothesis testing, correlation, regression, design of experiments, Taguchi robust design, and a lot more.
Pre-requisites
There are no specific pre-requisites for this course.
Estimated Time
