Statistics Unit Test KCA Unit 8 Lesson 12

These are 100% correct...remember they may change up the order or even the questions themselves. Learn this stuff so you at least understand what they are looking for!

1. Lora asks her neighbors how much water they drink each day.
2. Choose the dot plot with 1,4,0,6,4
3. From 10 to just under 14
4. 72
5. The mean 11.5; The median 11.5; The spread 3
6. mean temperature 51 degrees; median temperature 50 degrees.
7. 2 (for median)
8. First quartile = 5; Third quartile = 19
9. The range is 6, and the interquartile range is 3.
10. 95
11. 38.4
12. The IQR is 2.5. This means that 2.5 hours is the range of the number of hours spent on the project for the MIDDLE 50% of the students.
13. IQR; the distribution is SKEWED, and there are outliers in the dataset.
14. IQR; the data distribution is SKEWED.
15. This one you will have to do yourselves. DON'T BE LAZY! You need to come up with an example that is at least 10 data points long and explain why YOU think the mean, median or mode is most affected by outliers. ANY 10 data point number will do!
I chose median as the one most affected by outliers 10+5+5+10+15+25+5+55+20+5 and worked for my solution.

GOOD LUCK!
