what is the mean absolute deviation of the data set 2,2,5
A.0
B.2/3
C.4/3
D.1/3
It's 4/3 for connexus

mean: 3
difference: 1,1,2
mean difference=4/3
Wahhhhh im cry
Is everything okay? Can I help you with anything else?
Well, calculating the mean absolute deviation involves finding the average of the absolute differences between each data point and the mean of the data set. So, let's break it down!
First, we need to find the mean of the data set 2, 2, and 5. Adding them up gives us a sum of 9. Since there are three values in the data set, the mean would be 9/3 = 3.
Next, we need to find the absolute deviations from the mean for each data point. For 2, the absolute deviation would be |2 - 3| = 1. For the other 2, it would also be 1. Lastly, for 5, it would be |5 - 3| = 2.
Adding up the absolute deviations gives us 1 + 1 + 2 = 4.
To find the mean absolute deviation, we divide the sum of absolute deviations (in this case, 4) by the number of data points (which is 3). 4/3 is equal to 1 and 1/3.
So, the mean absolute deviation for the data set 2, 2, 5 is D. 1/3. And if you excuse my mathematical pun, it seems this problem is all about "mean" jokes!
To find the mean absolute deviation (MAD) of a data set, follow these steps:
1. Find the mean of the data set. To do this, add up all the numbers and then divide by the total count of numbers.
For the data set 2, 2, 5:
Mean = (2 + 2 + 5) / 3 = 9 / 3 = 3
2. Find the absolute deviation of each number from the mean. The absolute deviation is the absolute value of the difference between each number and the mean.
For the data set 2, 2, 5 and mean 3:
Absolute deviation from 3: |2 - 3| = 1
Absolute deviation from 3: |2 - 3| = 1
Absolute deviation from 3: |5 - 3| = 2
3. Find the average of these absolute deviations. To do this, add up all the absolute deviations and then divide by the total count of numbers.
For the data set 2, 2, 5:
Average absolute deviation = (1 + 1 + 2) / 3 = 4 / 3
So, the mean absolute deviation of the data set 2, 2, 5 is 4/3.
Therefore, the correct answer is option C. 4/3.
