Hello! I didn't come to type nonsense like the usual days! I came to revise this time! ^^ Let's start before I go for lunch..

HM. Today.. It's RHT! Good luck to me.

Chi-square test of independence :
Step 1.
Ho : there is no relationship btw ... and ...
H1 : there is relationship btw ... and ...
step2.
alpha : 0.05? 0.01? 0.1? blah.
step3. Test statistics(given)
df : given
step4. critical value(given)
*draw curve
step5. Make decision.
If test statistics is more than critical value, we reject H0.
Therefore, we conclude that there is relationship.
If test statistics is less then critical value, we do not reject H0.
We conclude that there is no relationship.

Sampling methods:
-limitation of time and money
-amt of resources available
-nature of problem
-??
-??

Probability sampling:
-systematic sampling : choose respondents according to a number sequence
-simple random sampling: choose respondents randomly
-stratified sampling: separate respondents into subgroup with a representative representing each group
-cluster sampling: differentiate respondents according to which subgroup they belong in

Non-probability sampling.
-convenience sampling: select respondents according to convenience Eg. shopping mall
-judgemental sampling: select people accroding to one's own personal judgement on a person based on characterisitcs.
-Quota sampling: a min number of respondents from each subgroup to be interviewed
-Referral sampling: respondents introduced other suitable respondents to be interviewed

Research process:
1. define the problem
2. development of objectives
3. plan research design
4. data collection
5. data analysis
6. preparation of report/presentation

Primary Data: data which one collects through surveys,interviews,questionnaires.
First hand data. Researcher is pri user.

Secondary Data: data which has already been collected by someone else, data which already exists. Researcher is sec user.

Guideline for ques wording:
-avoid double barrelled ques
-avoid ambigueous words
-avoid leading ques
-??

Pretesting is important as it allows the researcher to eliminate potential errors in the questionnaire and ensures the sequence of ques is smooth.

Fieldwork collection process.
1. Selecting of workers
2. trainning of workers
3. supervising workers
4. validating fieldwork
5. evaluating fieldwork

Okay! Back to studying!! ^^
