Descriptive Statistics (n=12)

The Descriptive Statistics (n=12) function computes the sample statistics for 12 numerical observations. It uses the n-1 design for samples, which is different from the N design used in population parameters.

Description

Enter 12 observations and choose a sample statistic from the following list:

• min - this is the minimum observed value
• max - this is the maximum observed value
• mean - this is the mean (average) of the observed values
• variance - this is the statistical variance of the observed values
• stdev - this is the standard deviation of the observed values
• sum - this is the sum of the observed values
• standard error - this is the the estimate of how far away the sample mean is from the population mean. This value is used to compute t-values for inferential statistics.
• Sum of Squares - this value is used to calculate t-values for inferential statistics.
• sum squared values - this is a part of the Sum of Squares value and is used in ANOVA calculations.
