is the study of the collection, analysis,
interpretation, presentation, and organization of
data. It is a method of collecting and summarizing
the data. This has many applications from a small
scale to large scale.
probability
ANOVA
Measure of Central Tendency
Statistics
denotes the possibility of the outcome
of any random event. The meaning of this term is
to check the extent to which any event is likely to
happen.
(a)
three basic categories of measures:
frequency distribution.
use measurements from
compare the treatment groups and make
generalizations about the larger
subjects.
(a)
types of inferential statistics
is a type of statistical analysis
in which you put your assumptions about a
population parameter to the test.
(a)
Meaning of confidence interval?
refers to the probability that
a set of values for a certain proportion of times.
is a set of statistical method used for
the estimation of relationships between a dependent
variable and one or more independent variable.
is a statistical method that
separates observed variance data into different
components to use for additional tests.
is a statistical hypothesis test
used in the analysis of contingency tables when
the sample sizes are large.
provides a very convenient
way of describing a set of scores with a single number that
describe the performance of the group.
Meaning of regression analysis?
refers to the probability that
a set of values for a certain proportion of times.

the estimation of relationships between a dependent
variable and one or more independent variable.

Population is the entirely of the group including all the
members that forms a set of
(a)
(a) every member of the
population has the chance of being selected. It involves
principle or randomization or chance.
what kind of sampling techique is this?
simple random sampling
not every member of the
population has the equal chance of being selected. It can rely
on the subjective judgement of the researcher.
Non-Probability Sampling
Probability Sampling
Selecting a sample based on the availability of the
member and/or proximity to the researcher.
Samples are chosen based on the goals of the study.
They may be chosen based on their knowledge of the study
being conducted or if they satisfy the traits or conditions set
by the researcher.
Snowball Sampling
non-probability sampling
Quota Sampling
Purposive Sampling
Proportion of the group in the population were
considered in the number and selection of the respondents.
Quota Sampling
Snowball Sampling
Probability Sampling
non proability sampling
