Answers
Step-by-step explanation:
Something that's stylish or cutting-edge can be called mod. ... Mod is informal slang for modern, and the two words can be used interchangeably. You can also use mod to talk about the specific 1960s subculture of young jazz and soul fans and motor scooter enthusiasts.
Step-by-step explanation:
The Mean
x¯¯¯=∑xN
Here,
∑ represents the summation
X represents observations
N represents the number of observations .
The Median
If the total number of observations (n) is an odd number, then the formula is given below:
Median=(n+12)thobservation
If the total number of the observations (n) is an even number, then the formula is given below:
Median=(n2)thobservation+(n2+1)thobservation2

Solved Examples
Question: Find the mean, median, mode, and range for the following list of values:
13, 18, 13, 14, 13, 16, 14, 21, 13
Solution:
Given data: 13, 18, 13, 14, 13, 16, 14, 21, 13
The mean is the usual average.
Mean = 13+18+13+14+13+16+14+21+139=15
(Note that the mean is not a value from the original list. This is a common result. You should not assume that your mean will be one of your original numbers.)
The median is the middle value, so to rewrite the list in ascending order as given below:
13, 13, 13, 13, 14, 14, 16, 18, 21
There are nine numbers in the list, so the middle one will be
9+12=102=5
= 5th number
Hence, the median is 14.
The mode is the number that is repeated more often than any other, so 13 is the mode.
The largest value in the list is 21, and the smallest is 13, so the range is 21 – 13 = 8.
Mean = 15
Median = 14
Mode = 13
Range = 8
