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
