##### How does the Expected Frequency Calculator work?
Free Expected Frequency Calculator - Given a contingency table (two-way table), this will calculate expected frequencies and then determine a conclusion based on a Χ2 test with critical value test and conclusion.
This calculator has 1 input.

### What 1 formula is used for the Expected Frequency Calculator?

Expected Frequency = (Row Total * Column Total)/N

##### What 7 concepts are covered in the Expected Frequency Calculator?
alternative hypothesis
opposite of null hypothesis. One of the proposed proposition in the hypothesis test.
H1
critical value
a point on the distribution of the test statistic under the null hypothesis that defines a set of values that call for rejecting the null hypothesis.
expected frequency
computed by multiplying the probability that an event occurs by the total number of possible times that the event could occur.
Expected Frequency = (Row Total * Column Total)/N
frequency
number of times a data value occurs
hypothesis
statistical test using a statement of a possible explanation for some conclusions
null hypothesis
in a statistical test, the hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling or experimental error.
H0
test statistic
a number calculated by a statistical test
