Creating Scatter Plots

Front

What does the y-axis represent in a scatter plot?

Back

The y-axis typically represents the dependent variable, which is the outcome or result being measured. In the context of the provided questions, it represents 'Amount Earned in Dollars.'

Front

What does the x-axis represent in a scatter plot?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed. In the context of the provided questions, it represents 'Hours Worked.'

Front

What is a scatter plot?

Back

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

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, used to make predictions about future data points.

Front

How can you use a trend line in a scatter plot?

Back

A trend line can be used to predict values by extending the line and finding where it intersects with the y-axis for a given x value.

Front

What is the purpose of creating a scatter plot?

Back

The purpose of creating a scatter plot is to visually display the relationship between two variables and to identify any trends or patterns.

Front

What does it mean if points on a scatter plot are closely clustered together?

Back

If points are closely clustered together, it indicates a strong correlation between the two variables.

Front

What does it mean if points on a scatter plot are widely spread out?

Back

If points are widely spread out, it indicates a weak correlation between the two variables.

Front

How do you interpret the slope of a line of best fit?

Back

The slope of a line of best fit indicates the rate of change between the two variables; a positive slope means that as one variable increases, the other also increases.

Front

What is correlation in the context of scatter plots?

Back

Correlation refers to the strength and direction of a relationship between two variables, which can be positive, negative, or none.
