# t.interval scipy

degrees_freedom = sample.size - 1

**Here is what the above code is Doing:**

1. We’re using the scipy.stats.ttest_ind function to calculate the T-test for the means of two independent samples of scores.

2. This function returns the T-statistic, and the p-value (see documentation here).

3. The T-statistic is a measure of how many standard errors there are between the two groups.

4. The larger the T-statistic, the more difference there is between groups.

5. The p-value is the probability that you would get the result you did (or more extreme) given that the groups are the same.

6. The smaller the p-value, the more evidence you have that the groups are different.
