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.
Descriptive 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

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
