Assignment 11.1 (Algebra I)

Front

What is the mean of a data set?

Back

The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.

Front

How do you find the median of a data set?

Back

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

Front

What is the mode of a data set?

Back

The mode is the number that appears most frequently in a data set. A data set may have one mode, more than one mode, or no mode at all.

Front

What does it mean if a data set has no mode?

Back

If a data set has no mode, it means that no number appears more than once.

Front

How do you calculate the mean of the following data set: 3, 6, 4, 10, x; Mean=6?

Back

To find x, set up the equation: (3 + 6 + 4 + 10 + x) / 5 = 6. Solving gives x = 7.

Front

What is the best measure of center for a data set with a mean of 13.2, median of 13, and no mode?

Back

The best measure of center is the mean, as it provides a balance point for the data.

Front

For a data set with a mean of 4.89, median of 4, and mode of 3, which measure of center is best?

Back

The best measure of center is the median, as it is less affected by outliers.

Front

How do you find the mean, median, and mode of the data set: 3, 2, 2, 3, 4, 20, 3, 2, 4?

Back

Mean: 4.78, Median: 3, Mode: 2 and 3.

Front

Calculate the mean, median, and mode for the data set: 5, 9, 4, 2, 5, 6, 7, 5, 9, 1, 9, 4.

Back

Mean: 5.5, Median: 5, Mode: 5 and 9.

Front

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

Back

The median is significant as it represents the middle value, providing a better measure of center when data is skewed.
