This week, working on my subsetted Marscrater data, I’m going to use a moderator to further examine my research question in the context of a Pearson Correlation.Research Questions:Is crater diameter associated with crater depth?Does the location of a crater on Mars (MARS_REGION) moderate the relationship between crater diameter and crater depth?Variables:I will be working with […]

This week, working on my subsetted Marscrater data, I’m going to examine a new research question in the context of a Pearson Correlation using linear regression model.Research Question:Is crater diameter associated with crater depth?Null Hypothesis (H0):Crater depth is not associated with crater diameter.Alternative Hypothesis (H1):Crater depth is associated with crater diameter. I will be working with […]

This week I am going to use the Chi-square test of independence to test my Week 1 hypothesis about the relationship between crater depth and crater location using the Marscrater dataset. The research question again is, “does crater depth depend on crater location (crater latitude)?”For this analysis, I will use a categorical explanatory variable with […]

This is the first week of the Data Analysis Tools course, the second course in the Data Analysis and Interpretation specialization taught by Wesleyan University via Coursera. The Data Analysis Tools course is a continuation of the Data Management and Visualization course, which is the first course in the Data Analysis and Interpretation specialization. Previous […]
