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 trend line in a scatter plot represent?

Back

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

Front

How can you use a trend line to make predictions?

Back

You can use a trend line to predict values by finding the corresponding value on the trend line for a given input value.

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

What is the x-axis in a scatter plot?

Back

The x-axis is the horizontal axis that typically represents the independent variable in a scatter plot.

What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable in a scatter plot.

Front

How do you determine the number of chapters in a book using a scatter plot?

Back

You can determine the number of chapters by locating the total number of pages on the x-axis and finding the corresponding value on the trend line.

Front

What is the purpose of using scatter plots in data analysis?

Back

Scatter plots are used to visually assess relationships between variables, identify trends, and make predictions.

Front

What does it mean if data points are widely scattered in a scatter plot?

Back

Widely scattered data points indicate a weak correlation between the variables.
