I have done a research looking at different frequencies of abrasions (ablation, etc.) over time (in hrs) and my data mainly consists of zeros. As I am weak in statistics, I am unsure which statistics, if any, is appropriate for my data. Attached is an example of my data.

Originally, I had planned to do a regression analysis but I'm unsure if it will work, and all the other numbers that are not 0 were found to be outliers.

Will zero-inflation be an option?

    $\begingroup$ You have hardly any variation in your data, which really limits your options. $\endgroup$ – dlnB Mar 22 '19 at 22:01

    $\begingroup$ If the remaining data is very similar to the posted sample, there is nothing I personally could do with a regression except predict zero in all cases. $\endgroup$ – James Phillips Mar 23 '19 at 2:44

    $\begingroup$ What is the purpose of your analysis? That ought to be the primary determinant of what you do with the data! $\endgroup$ – whuber Mar 23 '19 at 14:11
  • $\begingroup$ The purpose of my analysis is to document trends for different settings and to observe the similarities/differences between the settings, but all of the settings resulted in similar results (i.e. having a lot of 0s and all non-0s identified as outliers). $\endgroup$ – user34930 Mar 23 '19 at 23:11
