Scatter Plot Review

Front

What is a scatter plot?

Back

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

Front

What does a positive association in a scatter plot indicate?

Back

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

Front

What does a negative association in a scatter plot indicate?

Back

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

What is the purpose of the equation m = 1.5L - 3 in relation to a scatter plot?

Back

This equation describes the linear relationship between the mass (m) of leaves and their length (L), allowing predictions based on the data.

Front

How can you find the predicted value of a variable using a linear equation?

Back

To find the predicted value, substitute the known value of one variable into the equation and solve for the other variable.

Front

What do the variables C and D represent in the equation y = Cx + D?

Back

C represents the slope of the line, indicating the rate of change, while D represents the y-intercept, indicating where the line crosses the y-axis.

Front

What does it mean if both C and D are positive in a linear equation?

Back

If both C and D are positive, the line slopes upwards and crosses the y-axis above the origin.

Front

How can you estimate values from a scatter plot?

Back

You can estimate values by finding the corresponding point on the plot that aligns with the given variable.

Front

What is the significance of the y-axis in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is affected by the independent variable plotted on the x-axis.

Front

What does it mean if a scatter plot shows no clear pattern?

Back

If a scatter plot shows no clear pattern, it suggests that there is no significant relationship between the two variables.
