| Difference
in Means Calculator
The
Difference in Means calculator allows you to
test for a statistically significant difference
between two population means drawn from independent
samples. The means are assumed to come from
normally distributed samples of distinct populations
with equal variances.
Typical
uses of a T-test for two independent samples
might include testing for differences in test
scores among students in two separate classrooms
or the average response to a given stimulus
for two study groups.
To determine
if the difference is significant follow these
steps:
- Plug in the means that you
wish to test.
- Plug in the sample size for
each of the independent groups.
- Enter the standard deviation
of each group.
- Select a confidence level.
- Click on Calculate.
