Statistics Calculator++

Not worth it

Very good

Correct me if I’m wrong - and really mean this, but I cannot find anywhere that I can put in whatever quaNtile -not quartile - I want and get the associated statistic critical value for specified alpha level. I also couldn’t figure out how to do alpha divided by two for two-sided interval in order to get once again a critical value. I was forced to do .02 or .03 (because it was an incremental dial where no in-between value of .025 be put in) but not the commonly interest 95% CI critical values for my binomial proportion (2-sided) N approx. I tried to input a proportion estimate with large n an normal distributed p-hat I but it I was required to state the number of trials and number of successes. Sometimes the information doesn’t come like that. sometimes it comes in the form of a proportion directly. The setup of the app was not intuitive for me.What is the opening page with a calculator on it? I wanted simple p-values for given x AND specified significance levels; critical values for doing my CI by hand…. I wanted something quick and handy over using SAS or R for these simple summary stats. Please correct me if I have over looked some of tour calculator’s function i have no problem being corrected. It seems to have a lot of features but i cant figure anything out of what I need to do for my assignments. Is there some no Manual for your Calc? What it is nice is that it shows you a graph of your distribution - now this is very helpful that i have not seen on other stat apps. I wish such could be generated for all input/output whenever possible. This seems to be well thought out. I was surprised to see confidence intervals for proportions. However as I said before I couldn’t figure out how to get the things I needed concerning them. If corrected i will gladly change my review. I want this Calc to work for me like on an open book exam rather than SAS. Also many many thanks for not collecting data. That’s unique also to this app and you developers. I did buy the full function version perhaps that you have resources to continue to perfect it and support of what you have done thus far - very very significant even if I don’t comprehend it. It’s super reasonably priced. Thank you again for this. Sorry for the harshness of your hard work - i just don’t get it.

I will try a couple times then I will no if it is not worth it

There is a few improvements but big one would be for you to swap input scores.

Súper color

The calculator is easy to use, straight forward ,and doesn’t have any problems I’ve found so far. Thanks!

It would be very helpful if instructions and teaching examples were attached. Overall well done and affordable. Thanks

I struggle in math and this made it so much easier.

Refund please!
