Is the conclusion of this study made by analyst on the basis of chosen sample reliable?

In order to answer this question, I would need more information about the study, the analyst, the chosen sample, and the conclusion that was made. Here are the steps I would take to evaluate the reliability of the conclusion:

1. Understand the Study: What is the purpose of the study? What are the research questions it aims to answer? What methodology was used?

2. Evaluate the Analyst: What is the analyst's background and expertise? Do they have a history of conducting reliable research?

3. Assess the Sample: How was the sample chosen? Is it representative of the population the study aims to understand? Was the sample size large enough to draw reliable conclusions?

4. Analyze the Conclusion: Does the conclusion logically follow from the data collected? Were all potential variables considered? Was the analysis conducted in a rigorous and unbiased manner?

5. Check for Peer Review: Has the study been peer-reviewed? This can often help validate the reliability of the conclusions.

Without this information, it's impossible to definitively say whether the conclusion of the study is reliable.
