Scatterplots and LOBF Review

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship of two data sets.

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit represents the trend of the data points in a scatter plot, indicating the general direction of the relationship between the variables.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in a scatter plot.

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 in the scatter plot.

Front

How do you identify an outlier in a scatter plot?

Back

An outlier can be identified as a point that is far away from the cluster of other points in the scatter plot.

Front

What is the purpose of the line of best fit?

Back

The purpose of the line of best fit is to summarize the relationship between the variables and make predictions.

Front

What is the formula for calculating the slope of a line?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

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

Back

The y-intercept represents the value of y when x is 0 in a linear equation.
