For the following expected and observed frequencies, find the Chi-Square obtained statistic (χ2obtained). 1st Category 2nd Category 3rd Category Observed (fO) 9 11 1 Expected (fe) 7 7 7 Group of answer choices 10.00 4.00 8.00 6.00
Added by Emily M.
Step 1
The formula is: \[ \chi^2 = \sum \frac{(f_O - f_E)^2}{f_E} \] where \(f_O\) is the observed frequency and \(f_E\) is the expected frequency for each category. Show more…

Let's say you are doing a Chi Square goodness of fit test and the total of the observed frequencies is 100. If the expected proportion for the first category is 0.25, then the expected frequency for that category is: 20 50 25 75
