Descriptive Statistics (n=10)

The Descriptive Statistics calculator computes the population and sample observational statistics for a set of comma separated number values (x).  The statistics include count, min, max, sum, sum of squares, mean, median, mid point, variance and standard deviation.

INSTRUCTIONS: Enter the following:

• (x) Set of Comma Separated Numeric Values (e.g. 4,-1.2,8,9 )
• (S) Choose a descriptive statistic or data function from the list:
  • count, min, max, sum (Σx), (Σx²), (Σx)², mean, median, mid point, range
  • var-pop, sd-pop, var-sample, sd-sample
  • sort up, sort down, rand

STATISTICS: The  calculator returns the chosen descriptive statistics.  Note, once the values of x are entered, you can choose any or all of the statistics and they will be displayed in turn without re-entering the values of x.  This calculator is a prominent feature with other statistical functions in the College Level Statistics Calculator (Stat Calc).

Note:

• 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.
