Identify the type of data provided by the information in each of the following columns of the table:
a. first b. second c. third
Step-by-Step Solution
Verifieda)The data in the first column is a qualitative variable, with "Product" as the variable under evaluation.
b) The data in the second column is a discrete quantitative variable, with the variable "Units shipped (millions)" as the focus.
c)The data in the third column is a continuous quantitative variable with the variable "Retail dollar value (millions)" as the focus.
Given in the question that a table
The table below contains data about physical shipments.
The shipment product is represented by the first column of the table.
The information is recorded in a non-numerical format. As a result, the Product is regarded as a qualitative variable.
Given in the question that,
The table below contains data about physical shipments.
The table's second column shows the number of units shipped (in millions) for each product.
The information is represented mathematically. As a result, the number of units shipped (in millions) is a numerical variable.
It is also possible to list the number of shipments. It is, thus, a discrete variable.
Given in the question that,
The data on physical shipments is represented in the table.
The Retail dollar value (in millions of dollars) for each product is represented in the table's third column.
The data is numerically recorded. As a result, the Retail dollar value (in millions of dollars) is a numerical variable.
Also, the retail dollar worth (in millions of dollars) that can be calculated from a range of values. As a result, it's a constant variable.
