Question 2(multiple choice worth 3 points) (14.11) given the data set below, what is the effect of removing the outlier 140 from the data set? {55, 57, 59, 62, 63, 140} the mean would decrease. the median would stay the same. the iqr would decrease. the median of the upper quartile would stay the same. question 3(multiple choice worth 3 points) (14.11) given the data set below, what is the effect of removing the outlier 100 from the data set? {12, 14, 18, 19, 19, 21, 27, 28, 100} the mean would increase. the median would stay the same. the iqr would increase. the median of the upper quartile would stay the same.

Q2. mean [ with 140 in place is] = 436/ 6 = 72 and 2/3rds.

mean [without 140 in place = 296/5 = 59.2

that means the mean would definitely decrease.

will get back to you in a moment.

Question 2:

The mean would decrease,

Mean is calculated by adding all the values from a data set together (I.e. 55+57+59+62+63+140) and than dividing that number by how many values were added; in this case that would be (436/6) which gives us 72.66666

If we take the knowledge learned from the explanation above and do the same thing but exclude the value of 140. ((55+57+59+62+63)/5)

which gives us 59.2 as our mean, which is decreased from 72.6666 that it was before.

I however do not know question 3 as I do not fully know IQR, sorry.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
