  1. 3. Is the science that deals with the collection, analysis and interpretation of all kinds of data.
  2. 5. Are those obtained from counting process where data are whole numbers, e.g. household size, number of cans of sardines produced.
  3. 6. A measurement of how far each number in a data set is from the mean (average), and thus from every other number in the set. mean is a weighted average of the possible values that the random variable can take. It is also called the expected value of X.
  4. 8. Has all the properties of the ordinal level. Data are consistent and meaningful, but it does not involve true zero point. Furthermore, since they are real numbers, all calculations can be performed.
  5. 10. A distortion or asymmetry that deviates from the symmetrical bell curve or normal distribution, in set of data.
  6. 11. Refers to the gathering of related information such as what is useful and needed, where to get information, and how to get information.
  7. 12. In this level are ranked but the degree of difference between them are not determined.
  8. 14. A body of information or observations being considered by the researcher.
  9. 15. The Table of Areas under the Normal Curve is also known as the ?
  10. 16. The sum of all the probabilities is (in word form).
  11. 17. Refers to extracting relevant information from the data at hand.
  12. 18. In this level are classified into categories. Names are used as labels. Numbers and letters are used to represent variables.
  13. 20. Is used to define certain observable values or characteristics. It is called a variable since the characteristics may vary from one another.

  1. 1. Those obtained through the measuring process where data are values that may be decimals or fractions, e.g. inflation rate,weight in kilograms.
  2. 2. A normal probability distribution that has a mean u = 0 and a standard deviation o = 1.
  3. 4. Is a measure of the amount variation of a random variable expected about its mean.
  4. 7. Is a numerical quantity that is generated by random experiment.
  5. 9. Refers to the systematic way of organizing data. It involves collecting, classifying and arraying, and presenting data gathered in preparation to its analysis.
  6. 13. Is a weighted average of the possible values that the random variable can take.
  7. 19. Has all the properties of the interval scale.In this level, there is a true zero point (an absolute value of zero) and multiplication and division of measurements can be performed.
