The middle number in a group of numbers (half the numbers in the group are higher than the median and half the numbers in the group are lower than the median) The highest numeric value in a group of numbers The number of cell locations in a range that contain a text or numeric character The number of cell locations in a range that contain a numeric character The average or arithmetic mean for a group of numbers Table 2.4 Commonly Used Statistical Functions Function In addition to demonstrating functions, this section also reviews percent of total calculations and the use of absolute references. This section demonstrates a variety of statistical functions that we will add to the Personal Budget workbook. However, when you use a function, you can highlight all the cells that contain values you wish to sum in just one step. This can be very time-consuming if you have to add the values in a few hundred cell locations. If you use a formula to add the values in a range of cells, you would have to add each cell location to the formula one at a time. Functions are more efficient than formulas when you are applying a mathematical process to a group of cells. A list of commonly used statistical functions is shown in Table 2.4. For example, the SUM function is used to add the values contained in a range of cells. Statistical functions apply a mathematical process to a group of cells in a worksheet. In addition to formulas, another way to conduct mathematical computations in Excel is through functions.

Learn how to set a multiple level sort sequence for data sets that have duplicate values or outputs.

Learn how to copy and paste formulas without formats applied to a cell location.

Use the MAX and MIN functions to find the highest and lowest values in a range of cells.

Use the AVERAGE function to calculate the arithmetic mean.

Use the COUNT function to count cell locations with numerical values.

Use absolute references to calculate percent of totals.

Use the SUM function to calculate totals.

In more technical terms, we would say that the data values never exceeded 3 standard deviations above or below the mean value of the dataset. Since the blue line (the raw data) never crosses the upper limit or lower limit on the chart, we would say that the process remained in a state of control for the entire duration of the data collection.

Yellow line: The lower limit of the process.

Grey line: The upper limit on the process.

Orange line: The mean value of the data.

Here’s how to interpret the lines in the chart:

The following statistical process control chart will appear: Lastly, we can highlight every value in the cell range A1:D21, then click the Insert tab along the top ribbon, then click Insert Line Chart. Step 4: Create the Statistical Process Control Chart

Next, we can use the following formula to calculate the upper and lower limits for the chart: #Upper limit calculation Step 3: Calculate the Upper & Lower Limits Next, we can use the following formula to calculate the mean value of the dataset: =AVERAGE( $A$2:$A$21) Step 1: Enter the Dataįirst, let’s enter the values for our sample data: The following step-by-step example shows how to create a statistical process control chart in Excel.

A statistical process control chart is a type of chart that is used to visualize how a process changes over time and is used to determine whether or not a process remains in a state of control.
