Final answer:
MIS tools such as scatter diagrams, histograms, and Pareto charts are commonly used to determine the causes of variances. These tools are important in techniques like Lean Six Sigma.
Step-by-step explanation:
MIS tools that analysts commonly use to determine the causes of variances include scatter diagrams, histograms, and Pareto charts. These tools are critical in the implementation of techniques such as Lean Six Sigma, which focuses on reducing process variations and improving efficiency.
A scatter diagram is a graphical representation of the relationship between two variables, allowing analysts to identify correlations or patterns in the data. Histograms provide a visual display of the frequency distribution of a set of data, allowing analysts to identify the distribution shape and outliers. Pareto charts are used to prioritize problems or causes by displaying them in descending order of frequency or impact, helping analysts focus on the most significant factors.
