Expected frequencies are what you would expect to happen based on chance. In statistics, expected frequencies are calculated by assuming that the observed frequencies follow a certain probability distribution. This distribution is determined by the characteristics of the data and the assumptions made about the underlying population.
Expected frequencies are often used in hypothesis testing and contingency table analysis. They provide a baseline against which the observed frequencies can be compared. If the observed frequencies deviate significantly from the expected frequencies, it suggests that there may be a relationship or association between the variables being studied.
In the given answer choices:
Explained variance refers to the proportion of the total variance in a dependent variable that can be explained by the independent variables in a statistical model.
Chance refers to the random occurrence of events without any predictable pattern or influence.
Dependent variable is the variable that is being predicted or explained in a statistical model.
Independent variable is the variable that is believed to have an effect on the dependent variable.
Therefore, the correct answer is "Chance".
