Module 16 Review

Front

What is the mean absolute deviation?

Back

The mean absolute deviation (MAD) is a measure of the dispersion of a set of data points. It is calculated by taking the average of the absolute differences between each data point and the mean of the data set.

How do you find the median of a set of scores?

Back

To find the median, arrange the scores in numerical order and identify the middle value. If there is an even number of scores, the median is the average of the two middle values.

Front

What is prime factorization?

Back

Prime factorization is the process of expressing a number as the product of its prime factors.

Front

What is the prime factorization of 45?

Back

5 x 3 x 3

Front

How do you create a histogram?

Back

A histogram is created by dividing data into intervals (bins) and counting the number of data points in each interval. The intervals are represented on the x-axis and the counts on the y-axis.

Front

What does it mean if a student received an allowance of exactly $15?

Back

It means that the student was given $15 as their allowance, which is a specific amount of money.

Front

How do you calculate the difference between two groups in a histogram?

Back

To calculate the difference, subtract the number of data points in one group from the number of data points in another group.

Front

What is a data set?

Back

A data set is a collection of related data points or values that can be analyzed.

Front

What is the significance of the median in a data set?

Back

The median provides a measure of central tendency that is not affected by extreme values, giving a better representation of the typical value in a data set.

Front

What is the purpose of calculating mean absolute deviation?

Back

The purpose is to understand how spread out the data points are from the mean, indicating the variability in the data.
