Question

Compute a Chi Square by hand with data set:

Answer 1

Answer #1

Chi-square is calculated using the following formula

where O is the observed frequency and E is the expected frequency.

hence the individual chi-square value is

The total chi-square value is 2.5 + 1.25+14.25+5.78 = 23.78
