Front

What does the slope of a line of best fit represent in a scatterplot?

Back

The slope represents the predicted change in the dependent variable (height) for a one-unit increase in the independent variable (first metacarpal bone length).

Front

How do you determine the number of data points that deviate from the line of best fit?

Back

Count the number of points whose actual values differ from the predicted values by more than a specified amount (e.g., 3 centimeters).

How do you calculate the probability of selecting a specific dress color?

Front

What is a scatterplot?

Back

A scatterplot is a graph that shows the relationship between two quantitative variables, with points representing individual data points.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, minimizing the distance between the line and all data points.

Front

What does it mean for a data point to be an outlier?

Back

An outlier is a data point that significantly differs from other observations, often lying outside the overall pattern of the data.

Front

How do you interpret the y-intercept of a line of best fit?

Back

The y-intercept represents the predicted value of the dependent variable when the independent variable is zero.

Front

What is the significance of the correlation coefficient in a scatterplot?

Back

The correlation coefficient measures the strength and direction of the linear relationship between two variables.
