Square Calculator - Online
Below you can find a Chi-square calculator. In probability and
statistics, the chi-square distribution with k degrees of
freedom is the distribution of a sum of k2
independent standard normal random variables. It’s one of the most
used probability distributions in inferential statistics.
This spreadsheet calculates the tail-end value for points on a
chi-square (X2) distribution curve. You must
enter the X2 value and the degrees of
Chi-square distribution curve
The unshaded area
represents the tail-end
value of X2.
The shaded area
represents the percentile.
distribution function is calculated using the following formulas:
v = degrees
Example: let's calculate percentiles and tail end
a given study was computed to be 3.2 with two degrees of freedom.
What are the tail-end and percentile values?
You enter your data:
Enter degrees of freedom
chi-square (X2) = 3.2
and get these results:
Tail end value = 0.2019
