So any test is acceptable. 10 Post hoc test result 55 56 2 Analysing Research Data This data consist of 150 subjects whom blood pressure were tested before and after 6 months weight management programme. Their weight (in kg) and blood pressure status before and after the intervention were recorded. 4 Compare Paired Means Independent sample t-test and one-way ANOVA are tests to be used when we compare independent5 means. When the means are dependent, or paired, those tests are no longer appropriate.
An example of a dummy table is given in Fig. 19. 1 999 1 = Male, 2 = Female None Statistical analysis 1. Check normality of glu 2. If glu Normal, run Independent sample t-test; if glu not Normal, run Mann-Whitney U-Test 3. n) SD = Standard deviation Fig. 10 Critical Information in Research Proposal In summary, the critical part in planning a research are: 1. 2. 3. 4. Good summary of literature search represented as a conceptual framework SMART-ly phrased objectives Complete and detail data dictionary Clear dummy table Anyone who is able to provide these four information in their research proposal should face only little problem when doing their research.
7 Observations and Measurements 27 Fig. 7 28 1 Planning a Research The characteristics or a normal distribution are: 1. 2. 3. 4. 5). SPSS Analysis: Check data distribution 1. 2. 3. 4. 5. 6. 7. 8. 1 Descriptive statistics for weight The Descriptives table describes the weight variable. 0 kg. 492. These information, together with the Histogram (Fig. 17), suggest that the observed body weights are normally distributed. If the data do not follow these characteristics, we can transform the data. Common transformation includes logarithm, exponentiation or inversion; or we could describe and analyse them differently.
