calculation student coefficient in python

To calculate a student's coefficient (also known as student's t-value) in Python, we can use the statistics module which provides a stdev function to calculate the standard deviation of a given list of values.

Here's an example code block that demonstrates how to calculate a student's coefficient for a sample dataset:

main.py
import statistics

# Sample dataset
data = [80, 85, 90, 92, 95]

# Calculate the mean of the dataset
mean = sum(data) / len(data)

# Calculate the standard deviation of the dataset
stdev = statistics.stdev(data)

# Define the sample size
n = len(data)

# Calculate the Student's coefficient
student_coef = (mean - 90) / (stdev / (n ** 0.5))

print("Student coefficient:", student_coef)

The output will be the student's coefficient, which is a measure of the number of standard deviations the sample mean is from the population mean. The larger the coefficient, the further away the sample mean is from the population mean, and the less likely it is to be a random observation.

Note that in the example code above, we assumed a population mean of 90. If you have a different population mean, you will need to adjust the code accordingly.
