Range, Width, min-max Values and Graphs
2
Let us assume that we have 20 workers and they are installing different number of (let us say cars) weekly. Each worker assemble different numbers. Let us find the min-max numbers, range, width of the distribution. The let us draw the the histogram of the distribution.
9
The minimum value is 20 cars and the maximum value is 40 cars
Range=highest value – Lowest Value Range is 40-20=20 into interval scale. İn order to find the width we need to classify the observations
14
Number of Cars Frequency 20-25 4 26-30 5 31-35 2 36-40 9 Total 20
15
Width= Range/The Number of Classes
16
The Percentage and Cumulative
Number of Cars Frequency Percentage Cumulative 20-25 4 20 26-30 5 25 45 31-35 2 10 55 36-40 9 100 Total -- Let us calculate The Weekly Average We need the middle value for each classes (20+25)/2=22,5 (26+30)/2=28 (31+35)/2=33 (36+40)/2=38
17
(22,5x0.2)+(28x0.25)+(33x0.10)+(38x0.45) = 31.9 = 32 Cars
Number of Cars Mid Classes Frequency Percentage Cumulative 20-25 22,5 4 20 26-30 28 5 25 45 31-35 33 2 10 55 36-40 38 9 100 Total -- (22,5x0.2)+(28x0.25)+(33x0.10)+(38x0.45) = 31.9 = 32 Cars
