Scatter Plot Flashcard

Front

What is a scatter plot?

Back

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

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 increases.

Front

What does a negative correlation indicate in a scatter plot?

Back

A negative correlation indicates that as one variable increases, the other variable decreases.

Front

What does it mean if there is no correlation in a scatter plot?

Back

No correlation means that there is no discernible relationship between the two variables.

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 scatter plot.

Front

How can you determine the line of best fit visually?

Back

You can determine the line of best fit by drawing a line that minimizes the distance from all points to the line.

Front

What is linear regression?

Back

Linear regression is a statistical method used to find the line of best fit for a set of data.

Front

What is the formula for a linear equation?

Back

The formula for a linear equation is typically written as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent in a scatter plot?

Back

The slope represents the rate of change between the two variables.

Front

What is the y-intercept in a linear equation?

Back

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