Statistics Analysis

The data for variables A, B, C, and D is presented in the table below

A B C D

1 white 72 -4.6 40
2 black 74 -4.7 47
3 red 68 -5.1 49
4 gray 70 -1.2 47
5 gray 70 3.1 55
6 white 72 7 61
7 red 68 9.9 86
8 black 74 9.3 85
9 gray 72 6 89
10 red 72 1.4 66

The variable A is the color of the car passing by as I looked through my window. Guided by the requirements of this assignment, I recorded the colors of first 10 cars. Operational definition for one of the groups of variable A, color white – the color which looks visually as the standard sheet of paper or pure cotton wool. Variable B is my pulse rate measured over 30 seconds and doubles. Variable C represents the monthly average high temperature (°C) in Nuuk, Greenland, and variable D is the average monthly precipitation in Nuuk in January to October, 2019.

The most appropriate way to graph A would be to use bar graph:

For variable B, time series (since heart rates were measured consecutively) would be more appropriate:

The frequency table for variable B will look as follows
Heartrate Frequency
68 2
70 2
72 4
74 2
