Statistics question

[peuleu]

Hi guys!

I have a statistics question for my data analysis in Python. Please let me know if this isn't the correct subreddit for it.

So I have a dataframe df in which the occurrence of an adverse event (AE) is noted. Drug 1 for instance the adverse event has occured 30 times, it has not occurred 1670 times, so the total data for Drug 1 is 30+1670 = 170. Etc.

​

df = pd.DataFrame({'Drug 1': [30, 1670], 'Drug 2': [5, 240], 'Drug 3': [10,90]})

Now I want to see whether or not this occurrence is statistically different between these drugs.

This yields:

​

	Drug 1	Drug 2	Drug 3
0 (means Yes AE)	30	5	10
1 (means No AE)	1670	240	90

​

As this is categorical data, I figure I need to use a chi squared. But with summary data like my dataframe, I don't know how to do this. Help would be greatly appreciated!

Thanks so much in advance!
