Final answer:
Isabel's weekly pay is the dependent variable because it changes based on the amount of data she enters hourly, making the data entered the independent variable that affects her pay.
Step-by-step explanation:
In the scenario provided, Isabel's weekly pay depends on the amount of data she enters each hour at her part-time job. The dependent variable is the variable that is affected by another variable, known as the independent variable. In Isabel's case, the dependent variable is the weekly pay she earns. This is because her pay changes in response to the amount of data she processes, which means the weekly pay (dependent variable) is a function of the amount of data entered (independent variable).
Understanding the relationship between independent and dependent variables is crucial in various fields such as business, economics, and research. It helps in establishing cause-and-effect relationships, where the independent variable influences the outcome or dependent variable
