1

It is raw information or facts that become useful information when organized in a meaningful way. It could be of qualitative and quantitative nature.

Data

Census

3

It uses sampling which is a selection of a subset within a population, to yield some knowledge about the population of concern.

Sample Survey

4

This is performed when there are some controlled variables and the intention is to study their effect on other observed variables

Experiment

5

This is appropriate when there are no controlled variables and replication is impossible.

Observation Study

6

It is any sampling method where some elements of the population have no chance of selection or where the probability of selection can’t be accurately determined.

Non-Probability Sampling

7

It is possible to both determine which sampling units belong to which sample and the probability that each sample will be selected.

Probability Sampling

8

All samples of a given size have an equal probability of being selected and selections are independent.

Simple Random Sampling

9

Participants are selected using a fishbowl

Simple Random Sampling

10

It is concerned with “looking after” and processing data.

Data Management

11

Relies on dividing the target population into strata (subpopulations) of equal size and then selecting randomly one element from the first stratum and corresponding elements from all other strata.

Systematic Sampling

12

When the population embraces a number of distinct categories, the frame can be organized by these categories into separate “strata”.

Stratified Sampling

13

Sometimes it is cheaper to ‘cluster’ the sample in some way (e.g. by selecting respondents from certain areas only, or certain time-periods only).

Cluster Sampling

14

In this method, there are two (2) samples in which the members are clearly paired, or are matched explicitly by the researcher (for example, IQ measurements or pairs of identical twins).

Matched Random Sampling

15

In the given data, 4 3 1 6 1 7 What is the mean

3.66

16

In the given data, 4 3 1 6 1 7. What is the Median

3.5

17

In the given data, 4 3 1 6 1 7 what is the Mode?

1

18

It determines if a sample data matches a population.

Chi-square goodness of fit test

19

Compares two (2) variables in a contingency table to see if they are related. It tests to see whether the distributions of categorical variables differ from each other.
