Determine the iqr of this data set. then indicate whether the data set contains any outliers. explain how you determined this.

10 13 15 12 12 4 12 17
12 13 15 18 10 11 20 19

The IQR of the data set is 4.5

Step-by-step explanation:

Given:

10 13 15 12 12 4 12 17

12 13 15 18 10 11 20 19

Now, to determine the IQR (interquartile range) of this data set.

So, we need to set the data in numerical orders:

4 10 10 11 12 12 12 12

13 13 15 15 17 18 19 20

Now, we split this in half and get the medians of both half:

4 10 10 11 12 12 12 12      Median 1 = 11.5

13 13 15 15 17 18 19 20   Median 2 = 16

Getting the medians of both half now we subtract the median 1 from median 2:

IQR = 16 - 11.5

IQR = 4.5.

Therefore, the IQR of the data set is 4.5

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
