When data are collected using a quantitative, ratio variable, a frequency distribution that summarizes the data is the upper and lower class limits must be calculated is the correct answer.
In this question,
A frequency distribution is used to display the number of observations within a particular interval. It groups data into categories, and records the number of observations in each category.
Frequency distributions are visual displays that organize and present frequency counts so that the information can be interpreted more easily. It is a graphical or tabular representation of data that shows the number of observations within a given value.
It provides the information of the number of occurrences (frequency) of distinct values distributed within a given period of time or interval, in a list, table, or graphical representation.
From the definition, when data are collected using a quantitative, ratio variable, a frequency distribution that summarizes the data is the upper and lower class limits must be calculated is the correct answer.
