Statistical Hypotheses

Level of Measurement

Descriptive statistics (i.e. at least one measure of central tendency and one measure of spread per data set & rationale for the measures selected) , Outlier Check (how you checked and why you used that method)

Visualization of the data (i.e. one figure per data set & a description of the figure and why that figure was the appropriate choice)

Statistical methods: description of the inferential test selected (i.e. type of z-test, t-test, or ANOVA) and rationale for why that inferential test was selected , Summary of all statistical findings, including the results from any assumption checks and inferential test results , Summary statement interpreting the results (i.e. what do the results mean)

1)A researcher was interested in studying the best way to teach suturing and casting to surgical residents. To study this, all incoming orthopaedic residents were divided into three groups: a standard training group scheduled to work in the emergency department (n=8), an instructor- led surgical skills boot camp group (n=8), and student-led surgical skills boot camp group (n=8). After 7 days of the intervention, suturing and casting skills were measured through a simulation-based exam. The researcher wants to know whether average exam scores differ between the three groups.
