Determine whether the tests of proportion are used for the categorical or the numerical data.

2021-02-10
The categorical data is the data which describes the qualities of the objects under consideration, where as the numerical data is the measure of the data.
The test of proportion is used to test whether the population proportion is significantly equal to hypothesized value or not. It is based on the proportion of the responses of the population. For observing the response, the population is divided into two categories.
Therefore, the test of proportion is used for the categorical data.

Chi-square tests are nonparametric tests that examine nominal categories as opposed to numerical values. Consider a situation in which you may want to transform numerical scores into categories. Provide a specific example of a situation in which categories are more informative than the actual values.
