Please help I have no idea what these are

1. Your Data Set:

Choose a random data set or look one up*

2. Where did your data set come from?

3. What is the mean of your data?

4. What is the median of your data?

5. What number describes the first quartile of the data?

6. What number describes the third quartile of the data?

7. What number describes the interquartile range?

8. Explain the meaning of the interquartile range as it relates to your data.

9. What is the mean absolute deviation of your data?

10. Explain the meaning of the mean absolute deviation as it relates to your data.

1-My data set is 2,2,4,6,8,8,6,1,3,3,5,6,11

2- I made up my own data set

3- The Mean of my data set is 5

4- The median is also 5

5- The first quartile is 2.5

6- The third quartile is 7

7- the inter quartile range is 4.5

8- the inter quartiel range is 4.5 because; to solve inter quartile range it is the differnece of the 75% quartile and the 25th percent quartile so the 25th percent quartile is 2.5 and the third quartile is 7. 7-2.5 is 4.5

9- The Mean Absuloute Deviation (MAD) is 2.3076923076923

Rounded to 2.3

10- The mean absolute deviation is the mean of the data absolute deviation in this case the absolute distance from the mean is the simplified definition which would be 2.3
