1. RESEARCH HYPOTHESIS AND METHODOLOGY

2. A research hypothesis is a tentative statement that suggests a possible explanation for a phenomenon or relationship between variables. Research Hypothesis

3. Null hypothesis is a statement that there is no significant difference or relationship between variables. Alternative hypothesis , on the other hand, is a statement that there is a significant difference or relationship between variables. There are two types of research hypotheses:

4. Type I and Type II Error

5. Research Design Sources of Data Participants of the Study Sampling Techniques Data Gathering Procedures Research Instrument Statistical Treatment of Data Gathered

6. Primary Secondary Data that come from an original source and are intended to answer specific research questions. Data that are taken from previously recorded data.

7. Process of selecting individuals who will participate as part of the study SAMPLING

8. Simple Random Sampling Process of selecting n sample size in the population via lottery

9. Give each population member a unique number Place numbers in bowl and mix Randomly select n numbers Population members that have been selected based on their numbers will be part of the sample

10. HOW TO DETERMINE THE SAMPLE SIZE?

11. Systematic Sampling Process of selecting K th element in the population until the desired number of respondents is attained

12. Stratified Sampling Process of subdividing the population into subgroup and drawing member from each stratum

13. Cluster Sampling Process of selecting clusters from a population which is very large

14. Process of selecting a subgroup of individuals who are available for the study

15. Process of selecting base from judgment to select a sample which the researcher believe, based on prior info, will provide the data needed.

16. Process of selecting sample with an assigned quota Quota Sampling

17. Divide the sample population into subgroups  Figure out the weightage/number quota of subgroups Select an appropriate sample size Conduct surveys according to the quotas defined

18. A technique in which one or more members of a population are located and used to lead the researcher to other member of the population

19. Multi-stage sampling is a more complex form of cluster sampling which contains two or more stages in sample selection.
