Answer :
Certainly! Let's consider each of the statements given:
1. A regression line and a trend line are opposite terms.
- This statement is false. A regression line and a trend line are not opposite terms. In fact, they are related concepts used to describe the relationship between variables in a dataset.
2. A regression line and trend line are equivalent terms.
- This statement is true. A regression line and a trend line generally refer to the same concept. Both are used to illustrate the relationship between two variables. Specifically, they help show the general direction in which data points are moving and can be used to make predictions. Regression analysis is a statistical process for estimating the relationships among variables, and the resulting line from this process is often called a trend line.
3. A trend line represents only the smallest data points.
- This statement is false. A trend line does not specifically represent only the smallest data points. Instead, it attempts to show the overall direction or pattern in a set of data by summarizing all of the data points.
4. A trend line represents only the largest data points.
- This statement is also false. Just like the previous statement, a trend line does not specifically represent only the largest data points. It summarizes the trend by incorporating all of the data points.
Given these explanations, the correct statement is:
A regression line and trend line are equivalent terms.
This is the correct option based on the given choices.
