Question

1) Develop a Python program using modules, functions and lists to calculate the following statistics for each column of the data.csv file: a) Mean b) Variance c) Standard deviation d) Correlation between each two different columns For the mean use the following expression: $\bar{X} = \frac{1}{N} \sum_{i=1}^{N} x_i$ For the variance use the following expression: $\sigma^2 = \frac{\sum_{i=1}^{N} (x_i - \bar{X})^2}{N}$ The standard deviation is the square root of the variance.

          1) Develop a Python program using modules, functions and lists to
calculate the following statistics for each column of the data.csv file:
a) Mean
b) Variance
c) Standard deviation
d) Correlation between each two different columns
For the mean use the following expression:
$\bar{X} = \frac{1}{N} \sum_{i=1}^{N} x_i$
For the variance use the following expression:
$\sigma^2 = \frac{\sum_{i=1}^{N} (x_i - \bar{X})^2}{N}$
The standard deviation is the square root of the variance.

b) Variance
c) Standard deviation
d) Correlation between each two different columns
For the mean use the following expression:
X̅ = (1)/(N)∑i=1^N xi
For the variance use the following expression:
σ^2 = (∑i=1^N (xi - X̅)^2)/(N)
The standard deviation is the square root of the variance.

Step 1

Read the data from the data.csv file and store it in a list of lists. Each inner list represents a row in the file. ```python import csv def read_data(filename): data = [] with open(filename, 'r') as file: reader = csv.reader(file) for Show more…
