Question

1. Given the sample data set

s = [1,1,2,2,2,9,-5,-10,8,0]

1. Compute the mean, median, mode, variance and standard deviation on paper/ text editor. Show all calculation steps for full credit.
2. Compute and verify the above statistical quantities using python. You can use the statistics package. Feel free to modify the sample code provided in the pre-class material. Your code must clearly print out the required quantities when executed. The display on screen must clearly say what quantity is being printed (eg: “The mean is: 3.45”, etc.).

Answer 1

#source code:

import numpy as np
from scipy import stats
import math
arr=[1,1,2,2,2,9,-5,-10,8,0]
print("The mean is:",np.mean(arr))
print("The median is:",np.median(arr))
print("The mode is:",stats.mode(arr))
print("The variance is:",np.var(arr))
print("The standard deviation is:",np.std(arr))

#output:

#if you have any doubts comment below..if you like give thumbs up...
