​ 13,18,13,14,13,16,14,21,13
Averages
14
15
13
Mean
Median
Mode

Answer 1

Answer:

15,14,13

Step-by-step explanation:

In ascending order

X=13,13,13,13,14,14,16,18,21

Mean=Sum/Total

=135/9=15

Median=(n+1)/2 th observation

=10/2=5th obs=14

Mode= 13 since it has highest frequency

Answer 2

Finding the Mean, Median and Mode:

Step-by-step explanation:

$\ Given \ value:\\\\13, 18, 13, 14, 13, 16, 14, 21, 13$

$\ find: \\\\\ Mean= ?\\\\\ Median= ?\\\\\ Mode =?$

$\ formula: \\\\\ Mean = \frac{ \ Sum \ of \ number} {\ total \ of \ number}$

$\ Median = \frac{(n+1)}{2} \ \ \ \ \ \ \ \ where \ n \ is \ total \ numbers \\\\\ Mode = \ highest \ frequecny \ of \ the \ number$

$\ Solution: \\\\\ first \ arrange \ all \ number \ in \ assending \ order$

$\rightarrow \ Numbers: \ \ 13, 13, 13, 13, 14, 14, 16, 18, 21\\\\\rightarrow \ Sum \ of \ number \ = 135 \\\\\rightarrow \ total \ number \ = 9$

$\ Mean = \frac{\ sum }{\ total \ number} \\\\\rightarrow \ Mean = \frac{\ 135 }{9} \\\\\rightarrow \ Mean = \ 15$

$\\ Median =\frac{\ (n+1) }{2} \ term\\\\ \rightarrow \ Median = \frac{\ (9+1)}{2} \ term \\\\ \rightarrow \ Median = \frac{\ (10)}{2} \ term \\\\ \rightarrow \ Median = 5 \ term \\\\\rightarrow \ Median = \ 14$

$\\ Mode \ = \ highest \ frequency \ of \ the \ number\\\\ \rightarrow \ Mode = 13$
