Measures of dispersion are...

Values that represent the spread of a distribution

Values that tend to represent the center of a distribution

Values that represent the range of a distribution

Values that represent the accuracy of a distribution

Which of the following represents the average distance of each score from the mean?

Standard deviation

Range

Mode

Median

The larger the standard deviation, relative to the mean...

The more dispersed the distribution values are from the mean

The closer the distribution values are to the mean

The more likely the mean, media, and mode are equal

The more likely the mean is a good proxy of the population mean

The smaller the standard deviation, relative to the mean...

The closer the distribution values are to the mean

The more dispersed the distribution values are from the mean

The more likely the mean, media, and mode are equal

The more likely the mean is a bad proxy of the population mean

To calculate the standard deviation you use...

The mean, the number of values, and all the distribution values

The median, the number of values, and all the distribution values

The mode, the number of values, and all the distribution values

All of the distribution values, and the number of values only

If you have a mean of 100 and a standard deviation of 80,

The distribution values are relatively far from the mean.

The distribution values are relatively close to the mean.
