Presented below is a table that illustrates the different aspects of descriptive statistics:

2. Inferential Statistics

Incorporating inferential statistics into data analysis is critical for a dissertation. This statistical method involves concluding a larger population based on a sample of data. Using inferential statistics, researchers can make generalizations and predictions, thus gaining valuable insights into the overall population.

Probability theory is the foundation for inferential statistics, allowing researchers to analyze and interpret data effectively. It assists in determining the statistical significance of findings, indicating that observed differences or relationships are unlikely to have occurred by chance alone.

Hypothesis testing is a common inferential statistic employed by researchers. They formulate a hypothesis about the population and collect sample data to test it. Statistical tests like t-tests or analysis of variance (ANOVA) are used to assess whether the results support or reject the hypothesis.

Another crucial aspect of inferential statistics is the calculation of confidence intervals. Researchers employ confidence intervals to estimate the range of the true population parameter. For instance, a 95% confidence interval implies that there is a 95% confidence level that the true parameter falls within that interval.

3. Qualitative Analysis

When conducting qualitative analysis for your dissertation, it is crucial to have a systematic approach to derive significant conclusions from your data. One effective way to organize and analyze qualitative data is by utilizing tables.

Step 1: Accurately transcribe your interviews, focus groups, or other qualitative data sources.
Step 2: Create categories or codes representing your qualitative analysis data’s key themes or concepts.
Step 3: Segment your data based on these categories or codes, assigning each segment to the relevant category.
Step 4: Analyze each segment to identify patterns, relationships, and unique insights during your qualitative analysis.
Step 5: Record your findings in the table, noting the frequency or prevalence of each theme or concept in your qualitative analysis.
