Line of Best Fit Flashcard

Front

What is a line of best fit?

Back

A line that best represents the data on a scatter plot, showing the trend of the data points.

Front

How do you determine the line of best fit on a scatter plot?

Back

By visually assessing the data points and drawing a line that minimizes the distance from all points.

Front

What does a positive correlation indicate?

Back

As one variable increases, the other variable also increases.

Front

What does a negative correlation indicate?

Back

As one variable increases, the other variable decreases.

Front

What does 'no correlation' mean?

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope indicates the steepness of the line and the direction of the relationship between variables.

Front

What does the y-intercept represent in a linear equation?

Back

The value of y when x is 0, indicating where the line crosses the y-axis.

Front

How can you identify a positive correlation on a scatter plot?

Back

Data points trend upwards from left to right.

Front

How can you identify a negative correlation on a scatter plot?

Back

Data points trend downwards from left to right.
