Scatterplots and exponents2

Front

What is a scatterplot?

Back

A scatterplot is a graph that displays values for typically two variables for a set of data. Each point represents an observation in the dataset.

Front

How do you interpret a scatterplot?

Back

To interpret a scatterplot, look for patterns, trends, and relationships between the two variables. You can identify if the relationship is positive, negative, or non-linear.

Front

What does a positive correlation in a scatterplot 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 scatterplot indicate?

Back

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

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 scatterplot, showing the trend of the data.

Front

How do you determine if a line of best fit is accurate?

Back

An accurate line of best fit should minimize the distance between the line and all the data points, indicating it represents the trend well.

Front

What is the exponent rule for multiplying powers?

Back

When multiplying powers with the same base, you add the exponents.

Front

What is the exponent rule for dividing powers?

Back

When dividing powers with the same base, you subtract the exponents.

Front

What is a linear relationship?

Back

A linear relationship is a relationship between two variables that can be represented by a straight line on a graph.

Front

What is a non-linear relationship?

Back

A non-linear relationship is a relationship between two variables that does not form a straight line when graphed.
