Key Concepts

Research Objective

The research objective refers to the primary goal or question that the study aims to address. In the context of survey research, it typically involves assessing or understanding a particular behavior, opinion, or attitude within a specific population.

Sample

The sample is the group of participants selected from the broader population for the purpose of the study. It should ideally represent the larger population to make valid inferences. In survey research, the sample might consist of individuals defined by certain demographic criteria, such as age or location.

Descriptive Statistics

Descriptive statistics are numerical or graphical methods used to summarize or describe data collected in a study. They can include measures like percentages, averages, frequencies, or proportions, which provide a snapshot of the data's main characteristics without making generalizations beyond the data itself.

Conclusions

Conclusions are the interpretations or inferences drawn from the data analysis that extend the findings to a broader context. They represent the study’s final statements regarding what the data indicate about the larger population under investigation.
