Hello everyone! I have been trying to figure out what i should do to show correlations in my biology report about smoking and heart rate. I have conducted 41 trials with people who are Non smokers and exercise Smokers and exercise No exercise smokers Smokers and no exercise I have means, and standard deviations. What statistical test should i do to show that each group is different? should i use a student's ttest? 2. Relevant equations Ttest Chi square? 3. The attempt at a solution I think that ttest i good as i can compare the values and determine wheter they are due to chance or not. However i dont really know Thanks!
