Extract of sample "Criteria for Selecting the Project's Population and Sample Selection"

The sample size was 30 samples. However, the analysis of this data did not provide statistically significant results. More data was needed so 50 data samples were collected to achieve statistical significance.

 

C. What data source was used to collect samples?
The data was collected by means of observation of unleaded gasoline prices in local stations. Questionnaires were not used because key personnel determining the factors affecting price changes in gasoline was not accessible. Other data was collected by the use of interviews with gas station personnel to gather their opinion concerning possible causes for changes in gasoline prices.

QUESTION #7

A. What is Good Research?
Good research provides new and unbiased findings that are important to some entity or group of people. The researcher must not benefit from the outcomes and findings of the study to ensure the integrity of the findings. Information collected should best represent the population that is being tested. Good research utilizes the most appropriate data collection methods such as surveys, interviews, etc… and research tools such as periodical indexes, databases, and Web sites.

  1. Reflecting on your business project, which of the nine actions do you feel you (or your team) would improve next time around? Explain.

    D. What value can come from a research project when the null hypothesis is not rejected and there is no statistical significance?

If the null hypothesis is not rejected, then the alternative hypothesis is not accepted. This is because the initial sample of 30 records did not provide enough information to infer the statistical significance of the hypothesis to be tested.
