Question: A situation in my own personal life is doing payroll for an Injection Molding Company. I will be doing a Chi-square (one way example) between male and female employee’s attendance during a one month period, 160 hour required week period.

Calculate expected numbers for each individual cell. Do this be multiplying row sum by column sum and dividing by total number.

1^st cell (Male attendance) -- 286 x 314 divide by 606 =148.19

2^nd cell (female attendance)—286 x 292 divide by 606 = 137.80

Sum of (Observed - Expected) 2 Divide by Expected
