Scatter Plot P1

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional axis.

Front

What does the y-intercept represent 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.

Front

In the equation y = mx + b, what does 'm' represent?

Back

In the equation, 'm' represents the slope of the line, indicating the rate of change of y with respect to x.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

How do you identify the slope from a scatter plot?

Back

The slope can be identified by determining the rise over run between two points on the line of best fit.

Front

What is the formula for the slope-intercept form of a linear equation?

Back

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

Front

What is the significance of the slope in a linear equation?

Back

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

Front

How can you determine if a scatter plot shows a strong correlation?

Back

A scatter plot shows a strong correlation if the data points are closely clustered around a straight line.

Front

What does it mean if a scatter plot has no correlation?

Back

No correlation means there is no discernible relationship between the two variables, and the data points are scattered randomly.
