MMW LESSON 1237

It is obtained by adding all the values in your sample and dividing by the sample size.

• Range
• Mode
• Sample Mean

• Median

This is done when we add up all the values in the population (more values to add)

and we would divide by the population size.

• Median
• Mode
• Range
• Population Mean

This is used to find the mean of values of the data set that are not equally represented.

• Weighted Median
• Weighted Average
• Weighted Mode
• Weighted Mean

The measure of dispersion that removes negative signs by squaring all deviations

of each number from its mean and getting the average of the squared deviations.

• Mean Deviation
• Range
• Variance
• Standard Deviation

This is a rough estimate of the middle.

• Midpoint

• Midrange

• Midmode

• Midmax

The most frequently occurring number found in a set of numbers.

• Mean

• Median

• Mode

• Variance

The positive square root of the variance measures the spread or dispersion

of each value from the mean of the distribution.

• Interquartile range
• Mean deviation
• Range
• Standard deviation

The simplest measure of dispersion.

• Mean
• Standard Deviation
• Median
• Range

It is the middle value of the data set when it has been arranged in ascending order.

• Mean
• Mode
• Range
• Median

It indicates the extent to which values in a distribution are spread around the central tendency.

• Deviation
• Variability
• Measures of Variability

• Concentration
