Question

consider how the limits of nominal, ordinal, interval and ratio data affect the ability to chart. why are tables used to summarize ratio and interval level data? what type of data is in your charts?

Answer 1

we know that ratio and interval level data represents numerical data values, which can be either integer data values or decimal values.

In statistics or mathematics, we need data table for the purpose of calculation like addition, multiplication etc.

So, we use table to summarize ratio and interval level data because it allows us to do calculations and produce the desired soltuion

Chart does not require any mathematical calculation, it is just pictorial representation of data. So, we can use any one or more type of data in charts to represent the data.
