What is the average score?

Back

The average score is calculated by adding all the scores together and dividing by the number of scores. For example, if Devin scored 12, Levi scored 15, and Espy scored 18, the average is (12 + 15 + 18) / 3 = 15.

How do you determine the difference between two quantities?

Back

To find the difference, subtract the smaller quantity from the larger one. For example, if 8 people like purple and 3 like red, the difference is 8 - 3 = 5.

What is the cost calculation for services?

Back

To calculate the cost of services, multiply the rate by the number of hours. For example, if mowing costs $9 per hour, for 2 hours it would be 2 * $9 = $18.

What is a dependent variable in a graph?

Back

The dependent variable is the variable that is measured and affected in an experiment. It is plotted on the y-axis. For example, in a graph showing sales, 'Bicycles Sold' is the dependent variable.

How do you calculate the average of multiple trips?

Back

To calculate the average distance of trips, add all the distances together and divide by the number of trips. For example, if the trips are 14, 4, 6, and 12 miles, the average is (14 + 4 + 6 + 12) / 4 = 9 miles.

What is a graph?

Back

A graph is a visual representation of data that shows the relationship between different variables. It can help in interpreting trends and patterns.

Front

What does the x-axis represent in a graph?

Back

The x-axis typically represents the independent variable, which is the variable that is manipulated or changed in an experiment.

Front

What does the y-axis represent in a graph?

Back

The y-axis typically represents the dependent variable, which is the variable that is measured in response to changes in the independent variable.

Front

How do you interpret a bar graph?

Back

A bar graph uses bars to show the quantity of different categories. The height of each bar represents the value of that category.

Front

What is a line graph used for?

Back

A line graph is used to show trends over time. It connects data points with a line to illustrate how a variable changes.
