Question

Use the data set to create Stem and Leaf display. Also calculate Model value from the display.37, 33, 33, 32, 29, 28, 28, 23, 22, 22, 22, 21, 21, 21, 20, 20, 19, 19, 18, 18, 18, 18, 16, 15, 14, 14, 14, 12, 12, 9, 6

Answer 1

Answer:

 Stem and Leaf Display

Stem (Leading Digit)          

0          1         2            3

Leaf (Trailing Digits)

69      2244456888899       001112223889     2337

Frequency

2         13           12        4

Total Frequency = 31

 

Total data set values = 31

37, 33, 33, 32, 29, 28, 28, 23, 22, 22, 22, 21, 21, 21, 20, 20, 19, 19, 18, 18, 18, 18, 16, 15, 14, 14, 14, 12, 12, 9, 6

Arranging into Ascending Orders to get Model:

6,9,12,12,14,14,14,15,16,18,18,18,18,19,19,20,20,21,21,21,22,22,22,23,28,28,29,32,33,33,37

Mode is 18

Answer 2

$\underline { \pink {Mode :}}$

Mode is the value of the observation which occurs most frequently.

$Given \: data : 37, 33, 33, 32, 29, 28, 28, 23,\\ 22, 22, 22, 21, 21, 21, 20, 20, 19, 19, <strong>\</strong><strong>\</strong>\underline {\pink {18, 18, 18, 18,}}\\ 16, 15, 14, 14, 14, 12, 12, 9, 6$

Here, 18 occurred most frequently . i.e.,

( 4 times)

Therefore.,

$\red{ Mode \:of \:the \:data } \green { = 18}$
