Question

at first attempt to answer these without looking anything up.....then if you have to; use answers. .....put them into your own words. 1. define a positive correlation and write down an example of a positive correlation

Explanation:

Brief Explanations

A positive correlation is a relationship between two variables where as one variable increases, the other variable also tends to increase, and as one decreases, the other tends to decrease. For example, in general, the more hours a student spends studying (one variable), the higher their test scores (the other variable) tend to be. As study hours increase, test scores often increase too, showing a positive correlation.

Answer:

  • Definition: A positive correlation exists when two related variables change in the same direction, meaning an increase in one variable is associated with an increase in the other, and a decrease in one is associated with a decrease in the other.
  • Example: The amount of exercise a person does and their overall fitness level. Typically, as the amount of regular exercise (e.g., number of hours of exercise per week) increases, a person's fitness level (e.g., measured by endurance, strength) also tends to increase.
