Answer:
The sum should be 100% if percentages are used and 1 if proportion is used.
Step-by-step explanation:
A relative frequency distribution is a type of frequency distribution. This can be explained using the frequency table given below:
<h2><u>Student IQ-Score</u></h2>
Jake 12
Blake 10
Toby 18
<u>Harry 20</u>
<u>Total 60</u>
To calculate Relative Frequency Distribution using percentage:
We add the total IQ score 12+10+18+20 = 60
Then divide each individual IQ Score by the Total IQ Score multiply by 100
Jake will have 12/60 * 100 = 20
Blake will have 10/60 * 100 = 16.67
Toby will have 18/60 * 100 = 30
Harry will have 20/60 * 100 = 33.33.
To calculate Relative Frequency Distribution using 1:
We add the total IQ score 12+10+18+20 = 60
Then divide each individual IQ Score by the Total IQ Score.
Jake will have 12/60 = 0.2
Blake will have 10/60 = 0.17
Toby will have 18/60 = 0.3
Harry will have 20/60 = 0.33
The Relative Frequency Distribution Table becomes:
<h2><u>Student IQ-Score</u></h2>
Jake 12 <em> 20 0.2</em>
Blake 10 <em>16.67 0.17</em>
Toby 18 <em> 30 0.3</em>
<u>Harry 20 </u><em><u> 33.33 0.33</u></em>
<u>Total 60 </u><em><u>100 1</u></em>
