Exam 4: Looking at Data: Measures of Central Tendency

Statistics that describe the dispersion of scores around a typical score are known as measures of.

The sample mean is represented by.

The symbol typically used to indicate a mean in a journal article is.

The mean for the scores 17, 17, 19, 23, 24 is.

For the three scores 7, 8, 9, what is the sum of squares?

The mean for the scores 1, 2, 2, 7 is.

The sum of the differences of a set of scores about the mean of those scores is always.

For the set of scores 1, 1, 2, 2, 3, 4, 5, 5, 6, 6 the median is.

A frequency distribution that has only one most frequently occurring score is called.

If scores are measured with a nominal scale, then the only measure of central tendency that can be used is the.

Which of the following divides a frequency distribution in half?

When calculating the mean, the symbol indicates. $\Sigma$

The measure of central tendency most affected by extreme scores in a distribution is the .

The median for the scores 0, 0, 1, 1, 2, 2, 3, 3 is.

If a distribution is unimodal and symmetrical, then the.

For a distribution in which no score occurs more than once, which of the following is true?

The median.

The is found by calculating. $\frac { \sum X } { N }$

For the set of scores 1, 2, 3, 4, 5, 6, 7,.

When the scores in a distribution are positively skewed, the mean will have a value.
