Description

From the listing uploaded by “catappult”.

The tool simulates the sampling and t-test of two groups of independent, normally distributed data such as the treatment and the control arms of a clinical study. To carry out the simulation, the mean and the standard deviation of each group, which are unknown normally, need to be hypothetically specified. The simulation generates random numbers as samples based on the specified mean and standard deviation. It shows the relative distribution of the sampled data in the charts above and below the button Simulate, then it computes the sample statistics – mean, standard deviation, t value of Student’s t-test, one-tailed and two-tailed confidence levels. The simulator can help provide some sense about the outcome of a study under different scenarios (e.g. different standard deviations, sampling sizes). It can supplement power analysis. For example, suppose a study on a cholesterol lowering drug is about to be conducted and one measure of the outcome is the cholesterol level change in one month. In addition, it is hypothetically assumed that the mean and the standard deviation are -15 mg/dL and 20 mg/dL respectively for the medication arm. The corresponding parameters for the control arm are 0 mg/dL and 10 mg/dL. Different sample sizes can be entered to see how they affect the statistical significance of the difference between the treatment arm and the control arm. The standard deviations and the means can also be altered to see their effects. The same set of parameters can be run multiple times to see how the effect of the inherent random nature.

Trial Simulator APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Trial Simulator APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is 1c9dd7ad28781a51f23021d108a0120c.
