Line of best Fit

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot. It shows the general direction of the data points.

Front

How do you determine if a line is a good line of best fit?

Back

A good line of best fit minimizes the distance between the line and all the data points, ideally passing through the center of the data distribution.

Front

What is an outlier in a data set?

Back

An outlier is a data point that differs significantly from other observations in the data set, often appearing far away from the trend of the data.

Front

What does a positive correlation indicate in a scatter plot?

Back

A positive correlation indicates that as one variable increases, the other variable also tends to increase.

Front

What does a negative correlation indicate in a scatter plot?

Back

A negative correlation indicates that as one variable increases, the other variable tends to decrease.

Front

What does 'no correlation' mean in a scatter plot?

Back

No correlation means there is no apparent relationship between the two variables; changes in one do not predict changes in the other.

Front

How can you identify an outlier on a scatter plot?

Back

An outlier can be identified as a point that is significantly distant from the cluster of other data points.

Front

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

Back

Front

What is the slope of a line of best fit?

Back

The slope of a line of best fit indicates the rate of change of the dependent variable with respect to the independent variable.

Front

What is the y-intercept of a line of best fit?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.
