How do I perform a t-test in Python?

You can use the scipy.stats library to perform a t-test in Python. Do you have specific data you want to analyze?

Yes, I have two sets of data: [23, 21, 18, 30] and [22, 19, 25, 27]. How do I compare them?

You can use the ttest_ind function from scipy.stats. Here's how you can do it:

from scipy import stats

data1 = [23, 21, 18, 30]
data2 = [22, 19, 25, 27]

t_stat, p_value = stats.ttest_ind(data1, data2)
print('T-statistic:', t_stat)
print('P-value:', p_value)

What do the t-statistic and p-value tell me?

The t-statistic indicates the size of the difference relative to the variation in your sample data, while the p-value helps you determine the significance of that difference. A low p-value (typically < 0.05) suggests that the difference is statistically significant.
