Appendix Single-variable Statistical Calculation
<#053> Select single-variable (1-VAR) and input the following data:
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
<#054> Edit the data to the following, using insert and delete:
{0, 1, 2, 3, 4, 5, 6, 7, 9, 10}
<#055> Edit the FREQ data to the following:
{1, 2, 1, 2, 2, 2, 3, 4, 2, 1}
• Examples <#056> through <#059> all use the same data as
Example <#055>.
<#056> Calculate sum of squares of the sample data and sum of
the sample data.
<#057> Calculate number of samples, mean, and population
standard deviation.
<#058> Calculate minimum value and maximum value.
<#059> Performing standard normal distribution approximation on
the input sample data (from Example <#055>) produces
the probabilities shown below.
Distribution probability that is a value less than the
normalized variate when the sample value is 3 (P value for
normalized variate when X = 3)
Distribution probability that is a value greater than the
normalized variate when the sample value is 7 (R value for
normalized variate when X = 7)
