## potential page merging[edit | edit source]

Hi! This is a lot like my topic https://wiki.openhumans.org/wiki/Finding_relations_between_variables_in_time_series. Combine somehow? - User:DG

- Given that standard t-tests like this aren't really used for time series (or at least not in the way described here) I'd keep it separate for now, but we could think about a larger 'meta'-topic about statistical testing? - Gedankenstuecke (talk) 09:02, 4 March 2022 (UTC)

- I think I'll just go ahead and make a Statistical testing page as a general introduction to the topic and link to the time series & t-testing pages. - Gedankenstuecke (talk) 10:09, 7 March 2022 (UTC)

## Excel parameters[edit | edit source]

Currently the page says that the "2" parameter is for the type and is chosen because the samples are not of same length. Is this really the meaning of the parameter? 'type' sounds to me whether it's 'paired' or 'unpaired' data, which would go a bit farther than just having the same amount of observations in both categories: A 'paired' test would be comparing a series of 'before' and 'after' measurements, so each data point has a corresponding 'partner' :) - Gedankenstuecke (talk) 09:02, 4 March 2022 (UTC)

- I just read up on it and expanded the article with some background on choosing the parameters etc! I hope it didn't turn too technical - Gedankenstuecke (talk) 13:34, 4 March 2022 (UTC)
