Answer:
Answer:
A.1) 22,25,22,22,24,26,24,26,23
Mean: 23.78
Solution: (22+25+22+22+24+26+24+26+23)/9
= 214/9
= 23.78
Median: 24
Solution: 22, 22, 22, 23, 24, 24, 25, 26, 26
= (9+1)/2 = 10/2 = 5th Number
Mode: 22
Solution: 22, 22, 22, 23, 24, 24, 25, 26, 26
= Mode is the most repeated number
on the list in chronological order
therefore the mode is 22.
A.2) 23,24,24,24,23,25,25,26,27,28
Mean: 25
Solution: (23+24+24+24+23+25+25+26+27+28)
= 250/10
= 25
Median: 24.5
Solution: 23, 23, 24, 24, 24, 25, 25, 26, 27, 28
= there's no middle so we will get 24
and 25.
= (24+25)/2 = 49/2
= 24.5
Mode: 24
Solution: 23, 23, 24, 24, 24, 25, 25, 26, 27, 28
= Mode is the most repeated number
on the list in chronological order
therefore the mode is 24.
B.1) 61,104,65,23,254,34,115,71
Range: 231
Solution: 23, 34, 61, 65, 71, 104, 115, 254
Largest Number - Smallest Number
= 254 - 23
= 231
B.2) 55,61,78,97,82,100,125,130
Solution: 55, 61, 78, 82, 97, 100, 125, 130
Largest Number - Smallest Number
= 130 - 51
= 79
Note: Always arrange in chronological order first, so things will get easier for you.
