Statistics

This worksheet computes and plots data from two text files created using Notepad.exe. This worksheet can be used with different data files. Simply create a text file of data values with one value per row, right-select the following "data" command and select Choose File. Note that data is simply a variable and can be changed.

Example 2.1

The data for this example is in the file Table 2-1.txt. It was entered using Notepad.

Partial listing of data ->

Histogram

Residuals

Standard Normal Distribution Curve

Note: Data must be sorted for distribution to plot correctly.

Example 2.2

The data for this problem was entered into the file Ex2-2.txt using notepad.

Partial listing of data ->

Mathcad cannot determine

the mode since there are

two separate modes in the sample data.

Computing the standard deviation using Equation (2.10)

Histogram

Residuals

Standard Normal Distribution Curve

Note: Data must be sorted for distribution to plot correctly.
