Two way table conditional probability
WebProbabilities that only involve a subset of the things in a two-way table are called conditional probabilities For example with male and female students studying various languages, you might want to know the probability that a male student studies German WebAn "association" exists between two categorical variables if the row (or column) conditional relative frequencies are different for the rows (or columns) of the table. The bigger the differences in the conditional relative frequencies, the stronger the association between the variables. If the conditional relative frequencies are nearly equal for all categories, there …

The Central Limit Theorem: WebProbability of Two Events. Probability is the measure of the likelihood of an event occurring. It is quantified as a number between 0 and 1, with 1 signifying certainty, and 0 signifying that the event cannot occur. It follows that the higher the probability of an event, the more certain it is that the event will occur.
WebConditional Probability is the probability of event two (E 2) happening given that event one (E 1) has happened.
