`n = count(x)`
Enter a value for all fields
Statistical Count calculator counts the number of values in a set (X) of comma separated numbers.
INSTRUCTIONS: Enter the following:
X) Numeric Observations: This is the set of comma separated numeric values (e.g. 4,-1.2,8,9 )
Count (n): The calculator returns the number of value in the set of numbers.
The Math / Science
The count of values in a set is equal to the number of values or observation in a set including duplicates.
: This function accepts a table of numbers separated by commas and Observational Stats for any of the columns. This includes count, min, max, sum, sum of squares (Σx²), square of the sum (Σx)², mean, median, mode, range, mid point, rand, calculates observational statistics , rand, population variance, population standard deviation, the sample/experimental variance, sample/experimental standard deviation. sort up, sort down
: This function lets you enter a string of numbers separated by commas, a low and high range and a number of bins. It then computes how many of the observations are in each of the bins between the high and low values designated. Frequency Distribution
This computes the various parameters associated with the Paired Sample t-test: . Paired Sample t-test
: The is ANOVA (one way) one way analysis of variance
This (χ 2) Chi-Square Test: computes the Chi-Square value for an nxm array of data and provides the degrees of freedom.
: This Linear Regression through a set of X and Y observations. It also computes the regression coefficient (r). computes the regression line (least-squares)
: This is y = a + bx to predict values of Y. linear equation used with Linear Regression
: This provides the Wilcoxon statistics and critical value for two groups of numeric observations based on an alpha value and whether it's a one or two tailed test. Wilcoxon Signed Rank Test
