What is the formula to calculate the average (mean) of a set of numbers?

Back

Add up all the numbers and then divide by how many numbers there are.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

What is the significance of the mean in statistics?

Back

The mean provides a measure of central tendency, summarizing a set of numbers with a single value.
