... from the tables is 16.92 at 95% confidence. Since the critical value is smaller than the observed (5.8), we can reject the null hypothesis that the transitions are independent, thus there is a statistical dependence on the transitions from one lithology to the next. Geologically, this is to be expec ...

... Recognize when a test of goodness-of-fit, a test of homogeneity, or a test of independence would be appropriate for a table of counts. Understand the degrees of freedom for a chi-square test depend on the dimensions of the table and not the sample size. Display and interpret counts in a two-wa ...

Sample size calculation
... What size sample do we require to be able to detect our target difference between two groups with pre-specified power and significance level, given the variation in our sample? Target difference must: 1. be determined from previous experience / literature 2. Be sufficiently large to be clinically / ...
