Principles of Measurement

QuestionAnswer
Numbers have equal intervals measured from true zero = which level of measurement? Ratio
Numbers have equal interval but no true zero = which level of measurement Interval
Numbers indicate rank order in which level of measurement? Ordinal
Numerals are category labels in which level of measurement? Nominal
What is the lowest level of measurement? Nominal
Consists of categories coded by name, number, letter or symbol though none have quantitative value. Labels for ID. Nominal
Blood type, gender, handedness, type of mental illness and area code are examples of.... Nominal
this measurement scale requires categories to be rank ordered on the basis of an operationally defined characteristic or property. Ordinal
Data are organized into adjacent categories exhibiting a "greater than-less than" relationship. Ordinal
Normal>impaired>absent, none>minimal>moderate>severe, good>fair>poor, are all examples of Ordinal
Manual Muscle Test, funciton, and pn are examples of Ordinal
Calender years, degrees C and F are examples of Interval
What scale possesses the rank-order characteristics of an ordinal scale but also demonstrates known and equal distances between the units of measurement. Interval
What is the highest level of measurement? Ratio
This is an interval scale with a true zero. Ratio
ROM, height, weight, and force are examples of? Ratio
A measure computed for all potential observations in a population is a what? Parameter
A measure computed from actual observations on a sample is a what? Statistic
A measured characteristic of a population is a? Parameter
A measured characteristic of a sample is a? Statistic
Statistical procedures used for estimating population parameters and for testing hypothesis based on population parameters; for use with interval and ration measures. Parametric Stats
Set of statistical procedures that are not based on assumptions about pop parameters; used with nominal and ordinal scales. Non-parametric Stats
The degree to which scores are free from errors of measurement refers to? Reliability
Appropriateness, meaningfulness, and usefulness of data from measurement refers to? Validity

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
