Exam 1: Displaying the Order in a Group of Numbers Using Tables and Graphs

The number of times the various numbers on a roulette wheel come up, in the long run, form a(n)__________ frequency distribution.

A psychologist is interested in studying aggressive tendencies in people and develops a measure of this personality characteristic. Aggression has become a(n)__________ in the psychologist's study.

According to the table, what is the total number of patients in this sample who suffer from motor problems?

Researchers use __________ to draw statistical conclusions that go beyond the numbers actually collected in the research.

If you suffer from test anxiety, some useful advice is to:

Another name for an ordinal variable is a(n)__________ variable.

A researcher measures the eye movements of 100 participants as they read ambiguous words embedded within sentences. Because eye movements are measured in milliseconds, and there are likely to be many different times measured, the researcher decides to use a __________ to help make sense of these data.

The distribution of scores in a research study in the behavioral and social sciences is usually:

In some cases, researchers describe a distribution in terms of whether its tails have many or few scores in them. This aspect of the shape of a distribution is known as:

Consider the scores 2, 6, 7, 1, 7, 8, 5, 4. Which of the following would be the correct second line of the frequency table?

Place the five steps for making a frequency polygon into the correct order: 1. Along the left side of the page (y-axis), make a scale of frequencies that ranges from 0 at the bottom to the highest frequency for any value. 2) Connect the points with lines. 3) Make a frequency table. 4) Mark a point above each value with a height for the frequency of that value. 5) Put the values along the bottom of the page (x-axis).

According to the table, what is the most common types of cognitive problem faced by Alzheimer's disease patients?

When making a frequency table for a numeric variable, the list down the left edge of the page should include:

On a measure of social skills, the difference between scores of 6 and 7 has the same meaning as a difference between scores of 25 and 26. This measure is considered a(n)__________ variable.

A student theorizes that performance on a statistics exam will be related to the number of hours she spent studying. This student will be required to use __________ to test her theory.

Why might a frequency polygon include an extra value at the start and end along the bottom?

A distribution is called __________ when the pattern of frequencies on the left and right side are mirror images of each other.

In a histogram, the vertical (up and down)dimension displays:

An important difference between a histogram and a frequency polygon is that the frequency polygon:

A distribution in which the scores pile up on one end and are spread out on the other end is an example of a(n)__________ distribution.
