Sometimes an event will occur more than once, the number of occurrences is known as frequency, and the list of frequencies for all events in data is known as a frequency distribution.

Qualitative variable: A variable that is used for classification of individuals based on some attributes or qualities or characteristics are called categorical or qualitative variable. Overall qualitative data is non-numerical data.

Frequency distribution of qualitative data:

From the definitions of frequency distribution and qualitative data it is easy to infer the meaning of the frequency distribution of qualitative data. This is the list of the number of occurrence of the qualitative data that is, the frequencies of all different values that are represented in the data

Use of the frequency distribution of qualitative data:

Some of the most important uses of frequency distribution of qualitative data is: - It helps to organize the data in order to make it understand easily. - It reduces the difficulty of understanding the qualitative data, by giving the count of distinct values.

It is a chart that displays the distinct values of the qualitative data on a horizontal axis and the frequencies of those values on a vertical axis. It is O B. It is a listing of the distinct values and their frequencies. It is useful because it provides a table of the values of the observations and how often O C.

A statistic is an unbiased estimator of a parameter when (a) the statistic is calculated from a random sample. (b) in a single sample, the value of the statistic is equal to the value of the parameter. (c) in many samples, the values of the statistic are very close to the value of the parameter. (d) in many samples, the values of the statistic are centered at the value of the parameter. (e) in many samples, the distribution of the statistic has a shape that is approximately NormalFind the mean of the following data: 12,10,15,10,16,12,10,15,15,13.
