2. ### Which correlation coefficient is best suited to dichotomous variables (and why do my results feel intutiteivly wrong)

I have collected data that shows the days on which I fasted and if those days resulted in weight-loss. Null hypothesis: There is no statistically significant relationship between fasting and weight loss. Data Analysis: 1 The chart (see way below) is a visual representation of my data. The...
3. ### how to draw contingency table for repeated experiments(multiple samples)

the aim is to decide whether gene types can affect response to certain stimulus. there are 3 types of genes(G1-3), 3 kinds of responses(R1-3). in one experiment, dozens individuals from each gene group are involved, some of them (a) showed response 1, some showed R2, etc. so the contingency...
