Python Coding challenge - Day 755| What is the output of the following Python Code?

 

Code Explanation:

1. Importing the statistics Module

import statistics

The statistics module in Python provides functions to calculate mathematical statistics like mean, median, mode, variance, etc.

We need it here to compute mean, median, and mode of the dataset.

2. Creating the Data List

data = [2, 4, 4, 6, 8]

A list named data is created containing numbers.

Values: [2, 4, 4, 6, 8]

This dataset will be used for statistical calculations.

3. Calculating the Mean

mean_val = statistics.mean(data)

statistics.mean(data) calculates the average of the numbers.

4. Calculating the Median

median_val = statistics.median(data)

The median is the middle value when the data is sorted.

Data sorted: [2, 4, 4, 6, 8]

Since there are 5 numbers (odd count), the middle number is the 3rd value.

Median = 4.

5. Calculating the Mode

mode_val = statistics.mode(data)

The mode is the most frequently occurring value in the dataset.

In [2, 4, 4, 6, 8], the number 4 appears twice, more than others.

So, mode = 4.

6. Printing the Results

print(mean_val, median_val, mode_val)

This prints all three values:

Mean = 4.8

Median = 4

Mode = 4

Output:

4.8 4 4
