What Are Various Scale of Measurement Flashcards

When a scale has the properties of magnitude and equal intervals but not absolute 0

The measurement of temperature in degrees Fahrenheit and Celsius.

A scale that has all three properties (magnitude, equal intervals, and an absolute 0)

Would have properties of Fahrenheit and Celsius scales but also include a meaningful 0 point. Another example is the speed of travel.

Displays scores on a variable or a measure to reflect how frequently each value was obtained. one defines all the possible scores and determines how many people obtained those scores.

The unit for the horizontal axis in a frequency distribution.

Answers the question "what percent of the scores fall below a particular score (x). The propertion of scores that fall below a particular score. Specific scores within a distribution.

The arithmetic average score in a distribution.

The square root of the average squared deviation around the mean. It is not an average deviation, it does give approximation of scores above or below average. it is used as a measure of variability in the distribution of scores.

The average squared deviation around the mean. the standard deviation squared

The differnce between a score and the mean, divided by the standard deviation.

A standardized score system with a mean of 50 and a standard deviation of 10. mcCall's T can be obtained from a simple linear transformation of Z scores.

Refers to divisions of the percentile scale into groups. Are points that divide the frequency distribution into equal fourths.

The point on a frequency distribution marking the 50th percentile.

The interval of scores bounded by the 25th and the 75th percentiles.Is bounded by the range of scores that represents th middle 50% of distribution.
