8. Parallelogram with four equal sides. R hombus

9. Refers to numerical observation of any kind, as a branch of mathematics, it deals with the collection, analysis, presentation, and interpretation of data. Statistics

10. Involves the collection, organization, and presentation of data and the summary of important values that describe data. D escriptive Statistics

11. A statement or theory subjected to a test is called a  data . Hypothesis

12. It refers to the entire group of individual objects or items. It is usually denoted by n . Sample

13. This is a method in which behaviour is observed, recorded, and st Observation method

14. This method is easy to do but the preparation takes times. Questionnaire method

15. Refer to any quantitative or qualitative facts or information. Data

16. It refers to characteristics or categories which cannot be subjected to mathematical operations and are normally expressed using ordinary descriptive language. Qualitative Data

17. It refers to variables which can be found by counting. Discrete Variable

18. It is the midpoint or the middle value in a class.  Class Mark (CM)

19. It is the difference between the upper class boundary and the lower class boundary.  Class size (i)

20. It is the number of times a score appears in a distribution.  Frequency

21. It refers to any specific characteristics or attribute that describes a population or a sample. Variables

22. It refers to a variable which can occupy any value over a given range. It can obtain by measuring quantities. Continuous Variable

23. It is the difference between the highest number and the lowest number in a given set of data. Range (R)

24. It is any of the groups or categories in a frequency distribution table where each of the data belongs. Class or Class Interval

25. It is used to organize and present numerical information.  Statistical Table

26. It is used to organize and present numerical information.  Statistical Table

27. Using the frequency distribution table above, determine the following: Scores of 50 students in a Mathematics test 25 – 27 10 22 – 24 6 19 – 21 18 16 -18 11 13 – 15 5

28. Using the frequency distribution table, determine the following: Scores of 50 students in a Mathematics test 25 – 27 10 22 – 24 6 19 – 21 18 16 -18 11 13 – 15 5 The size of each class interval 3 The total frequency 50 The lowest class 13-15 The highest class 25-27 The class with the highest frequency  19-21

29. Using the frequency distribution table, determine the following: Scores of 50 students in a Mathematics test 25 – 27 10 22 – 24 6 19 – 21 18 16 -18 11 13 – 15 5 The class with the lowest frequency 13-15 The upper boundary of the highest class 27.5 The lower boundary of the lowest class 12.5 The class mark of the highest class 26 The class mark of the 2 nd  lowest class 17

30. Using the frequency distribution table above, determine the following: Scores of 50 students in a Mathematics test 25 – 27 11 22 – 24 7 19 – 21 19 16 -18 12 13 – 15 6

31. Using the frequency distribution table, determine the following: The size of each class interval 3 The total frequency 55 The lowest class 13-15 The highest class 25-27 The class with the highest frequency  19-21 Scores of 50 students in a Mathematics test 25 – 27 11 22 – 24 7 19 – 21 19 16 -18 12 13 – 15 6

32. Using the frequency distribution table, determine the following: The class with the lowest frequency 13-15 The upper boundary of the highest class 27.5 The lower boundary of the lowest class 12.5 The class mark of the highest class 26 The class mark of the 2 nd  lowest class 17 Scores of 50 students in a Mathematics test 25 – 27 11 22 – 24 7 19 – 21 19 16 -18 12 13 – 15 6
