Q. 2.46
Question
For quantitative data, we examined three types of grouping: single-value grouping, limit grouping, and cut point grouping. For each type of data given, decide which of these three grouping types is usually best, Explain your answers.
a. Continuous data displayed to one or more decimal places
b. Discrete data in which there are relatively few distinct observations
Step-by-Step Solution
Verified(a) The best grouping method for the given data is Cut-point grouping.
(b) The best grouping method for the given data is Single value grouping.
Continuous data displayed to one or more decimal places
Take a look at the information provided.
Continuous data with one or more decimal places presented.
When the data is continuous and given in decimals, the cut-point method is used. Cut-point grouping is the optimum grouping strategy for the supplied data.
The best grouping method for the given data is Single value grouping.
Take a look at the information provided.
Discrete data consists of a small number of distinct observations.
For discrete data with a small number of distinct values, the single value grouping method is useful.
As a result, single value grouping is the optimal grouping strategy for the supplied data.
