The study compares two ulcer therapies (A and B) with three variables: time of last visit in months, age in years and duration of disease. Write a persuasive report type essay.
Describe the statistical test and the reason for using it. Briefly describe the summary statistics of the participants. What conclusions can you draw and what recommendations could you provide based on this information?
In your analysis, and before providing your recommendations, please consider:
● group statistics ● the independent-samples t test ● homogeneity of variance ● probability that null hypothesis is correct ● t test limitations
Justify your recommendations based on your data analysis. Include specific reasons for each recommendation.
