The sampling distribution of the Chi-square statistic, X2 can be closely approximated by a continuous curve known as chi-square distribution.

As v changes, the probability function of Chi-square also changes. For very small numbers of degree of.

There are two type of frequency distributions which are used in statistics: grouped frequency distribution and ungrouped frequency distribution. The first one is utilized for a high quantity of data, when it is impossible to list all of them in the table (“Grouped Frequency.
