To analyze two quantities, such as the number of textbook pages and cost, one must collect bivariate data, enter it into a system, and calculate a linear equation. A table with columns for each quantity would organize the data for analysis.
To make a table of two quantities to be analyzed, we must first determine the system of interest and identify the known quantities. For example, if we are looking at the relationship between the number of pages in a textbook and the cost of the textbook, we might survey 10 textbooks, recording these two variables. Here are the steps you would typically follow:
- Collect bivariate data for each textbook, recording the number of pages and the cost.
- Enter this data into a calculator or computer.
- Use the data to calculate a linear equation that models the relationship between the pages and cost.
Once the data is collected, you can create a table with two columns; one for the 'Number of Pages' and another for 'Cost of Textbook'.
Number of Pages:- 200 | 350
Cost of Textbook:- $40.00 | $60.00
After completing the table, input the data into a statistical software or calculator to write the linear equation, rounded to four decimal places, which represents the relationship between the two variables.
The question probable may be:
What steps would you follow to analyze the relationship between the number of pages and the cost of textbooks? Provide a detailed process, including the collection of bivariate data, input into a calculator or computer, and the calculation of a linear equation. Additionally, what information would you include in a table summarizing the collected data?
