List of my Sample Projects involving Inferential Analysis.
Click on Project Name to View the Project.
- Comparison of Weight, Leaf Length, and Stalk Length: This Inferential Analysis involves comparison using Student's t-test and Welch t-test for Inferential Analysis. The research group is conducting an experimental study to check whether there is a significant difference between the control and treatment group in the weight (lbs), leaf length (mm), and stalk length (ft) post test measures. Samples for each group were determined via sample size estimation using power and mean, and randomization is considered in the assignment of groups.
- Comparison of Post Test Student Ratings between Control and Treatment Group: This Inferential Analysis involves the comparison of post test student ratings between Control and Treatment Group using Wilcoxon Rank Sum and Wilcoxon Signed Rank Exact Test. A research team is doing an experiment to assess whether there is a significant difference between the control and treatment group in the post test ratings of the students. The number of participants for each group were determined via sample size estimation using power and mean, and randomization is considered in the assignment of groups.
- Comparison of User Ratings between Traditional and New System Setup: >The company is planning to replace the traditional setup with a new system. Prior to the decision, a team has been formed to assess whether such move will lead to a marked improvement in user satisfaction ratings. The team will assess whether there is a significant difference between the control and treatment group in the post test ratings of the users. The number of users for each group were determined via sample size estimation using power and mean, and randomization is considered in the assignment of groups.
- Comparing Extent of Student Engagement across Different Academic Programs: A comparison on the extent of student engagement is to be conducted to check whether interventions would be needed to entice students to participate in school activities. The team randomly sampled students (proportional allocation) from the four Academic Programs offered by the school and met the desired sample size computed via Modified Cochran.
