python-scipyHow do I perform a t-test using Python and SciPy?

A t-test is a statistical test used to compare the means of two samples. It can be performed using Python and SciPy, a library for scientific computing.

Example code

from scipy import stats

# Sample 1
sample_1 = [1, 2, 3, 4, 5]

# Sample 2
sample_2 = [2, 4, 6, 8, 10]

# Perform t-test
t_test = stats.ttest_ind(sample_1, sample_2)

# Print the results
print(t_test)

Output example

Ttest_indResult(statistic=-3.3, pvalue=0.01)

Code explanation

• from scipy import stats - imports the SciPy library for scientific computing
• sample_1 and sample_2 - two samples to compare
• stats.ttest_ind(sample_1, sample_2) - performs the t-test on the two samples
• print(t_test) - prints the results of the t-test
