Create, Collect, and Analyze Surveys and Web Forms
Numeric Descriptive Statistical Reports require numeric entry survey questions.
A summary table is displayed above the descriptive statistics.
Fifteen Descriptive Statistical values are displayed for each numerical entry question. The 3 and 5 column numeric entry questions display separate statistics for each cell value.
Number of Values
This count does not include any empty values from the series of numbers being analyzed.
Maximum Value
This function finds the largest value in the series of numbers being analyzed.
Minimum Value
This function finds the smallest value in the series of numbers being analyzed.
Range
The range is found by subtracting the minimum value from the maximum value.
Sum
This function adds the values of the series of numbers.
Sum of Squares
This function calculates the deviations of the series values from the mean, squares those deviations, then adds those numbers to get a final result.
Mean
This is commonly called the average. It is calculated by adding the series values, and divided by the number of values.
Mode
This is the most common value in the series of numbers. If all values in the series are unique, no modal value is displayed.
Median
This function displays the middle value from the sorted set of values. Half of the values fall below, and half the values are above the median.
Standard Deviation
The standard deviation is used to measure how values are distributed around the mean.
Skew
The skew measures the symmetry of the distribution of values. If the distribution of numbers includes a greater number of larger values, it has a positive skew. If the distribution includes more lower values, it has a negative skew.
First Quartile
This value marks the 25th percentile.
Third Quartile
This value marks the 75th percentile.
Null Values
This is a count of empty values from the series of values being analyzed.
