If a store manager wanted to know how many customers arrived at his/her store each hour, which process metric would he/she need?
Naddika [18.5K]

If a store manager wanted to know how many customers arrived at his/her store each hour, the process metric would he/she need is the flow rate.

The flow measurement used to quantify the movement of bulk fluids is called flow rate. A known area's fluid velocity can be used to calculate flow. Tracer methods can be used to determine the flow rate from changes in dye or radioisotope concentration in very large flows. The volume of fluid that moves per unit of time is known as flow, also known as volumetric flow rate. When measuring the flow of water resources, different units are frequently used, including cubic feet per second (CFS), cubic meters per second (cms), gallons per minute (GPM), millions of gallons per day (MGD), and others.

A bar chart, sometimes known as a bar graph, is a type of chart or graph that displays categorical data using rectangular bars with heights or lengths proportionate to the values they indicate.

<h3>What is a bar graph used for?</h3>

Bar graphs are used to compare data across groups or to follow changes over time. When attempting to measure change over time, however, bar graphs work best when the changes are big.

Bar graphs are a powerful graphic to utilize in presentations and reports. They are popular because they enable the viewer to identify patterns or trends far more simply than a table of numerical data.

Thus, Option C is what Dana should use.
