Scatterplots Practice #1

Front

What is a scatterplot?

Back

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

Front

What does a positive association in a scatterplot indicate?

Back

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

Front

What does a negative association in a scatterplot indicate?

Back

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

Front

What does 'no association' mean in a scatterplot?

Back

No association means there is no clear relationship between the two variables; the data points are scattered randomly.

Front

How can you estimate values using a scatterplot?

Back

You can estimate values by looking at the trend line or pattern in the scatterplot to predict the outcome for a given input.

Front

What is a trend line?

Back

A trend line is a straight line that best represents the data points in a scatterplot, showing the general direction of the data.

Front

If a scatterplot shows a student with 6 absences getting a score of 76, what does this imply?

Back

It implies that there is a relationship between the number of absences and the final exam score, where more absences may lead to lower scores.

Front

What is the purpose of using scatterplots in data analysis?

Back

Scatterplots help visualize relationships between variables, making it easier to identify trends, patterns, and correlations.

Front

How do you interpret a scatterplot with a negative association?

Back

In a scatterplot with a negative association, as one variable increases, the other variable decreases, indicating an inverse relationship.

Front

What is the significance of the x-axis and y-axis in a scatterplot?

Back

The x-axis typically represents the independent variable, while the y-axis represents the dependent variable.
