Chapter 12: Q.12.9 (page 714)

Use the columns "year" and "# flu cases diagnosed. Why is 鈥測ear鈥� the independent variable and 鈥�# flu cases diagnosed.鈥� the dependent variable (instead of the reverse)?

Short Answer

Expert verified

The year happens in a natural way and it changes in a fixed interval so it is the independent variable and # flu cases diagnosed is dependent on years so it is the dependent variable.

Step by step solution

01

Given information

Given in the question that a table,

02

Solution

Here the year is a natural variable and it changes in a fixed interval of time so as a result the year will not dependent on any other factors.

Now in this case the year is an independent variable and the # flu cases diagnosed is dependent on the year.

# flu cases diagnosed is a dependent variable.
