What is a distribution that shows the number of data values less than or equal to a specific value usually an upper boundary )?

A cumulative frequency distribution ( CF) is a distribution that shows the number of data values less than or equal to a specific value (usually an upper boundary). It is obtained by adding the frequency for that class and all previous classes.

What is an item of interest that can take on many different numerical values?

A variable is a characteristic that can be measured and that can assume different values. Height, age, income, province or country of birth, grades obtained at school and type of housing are all examples of variables. Variables may be classified into two main categories: categorical and numeric.

Is the fraction or proportion of the total number of data items belonging to the class?

The relative frequency is the fraction or proportion of the total number of items belonging to a class. This definition is applicable to both quantitative and categorical (qualitative) data.

Are frequency tables quantitative?

The frequency table is usually used to summarize qualitative data, but it can also be used to summarize quantitative data by transforming it to qualitative data.
