A run chart would be used to:
Select one:
a. track the values of a variable over time
b. list potential causes of an effect
c. identify a source of problem
d. collect and organize the data
e. none of the choices
Answer: (a) Track the values of a variable over time.
Justification
A Run Chart is a graphical representation that includes the data that plotted or even collected over time. It is used to predict the trends or patterns from an observed or a set of collected data over a period of time.
And the rest of them given here are not what a run chart is used for, but all of them could be extracted out from a Run Chart as it's a process of collecting the data over a period of time. Most of the factors or variables that cause the fluctuations or variations in a Run chart will be noticed simultaneously at the time of plotting the data, which will help to understand the list of potential causes of an effect as well as the source of a problem from the collection and organizing of data.
