What is the range of the data set?{33.4, 31.7 ,31.3, 35.6, 33.4, 33.5, 38.8, 39.2, 38.8, 33.4, 37.8}

Answer 1

Answer:

The range of the data set {33.4, 31.7 ,31.3, 35.6, 33.4, 33.5, 38.8, 39.2, 38.8, 33.4, 37.8} is R = 7.9

Given details in the problem :

The data set : 33.4, 31.7 ,31.3, 35.6, 33.4, 33.5, 38.8, 39.2, 38.8, 33.4, 37.8

In statistics, The range is the spread of your data from the lowest to the highest value in the distribution. It is a commonly used measure of variability.

The range is calculated by subtracting the lowest value from the highest value. While a large range means high variability, a small range means low variability in a distribution.

Rearrange the given Data Set : 31.3, , 31.7 , 33.4, 33.4, 33.4, 33.5, 35.6, , 37.8 , 38.8, 38.8, 39.2,

The lowest Value of the data set is 31.3

The Highest value of the data set is 39.2

The formula to calculate the range is:

R =H- L

R = range

H = highest value

L = lowest value

R = 39.2-31.3

R = 7.9

The range of the data set {33.4, 31.7 ,31.3, 35.6, 33.4, 33.5, 38.8, 39.2, 38.8, 33.4, 37.8} is R = 7.9

1. 64 is the answer.

2. 144 is the answer

Step-by-step explanation:

First, multiply the numbers inside the parenthesis. So

1. 2*4 = 8

2. 6*2 = 12

Next, Use the exponents

1. 8^2

2. 12^2

Finally, solve using exponents.

1. 8^2 = 64

2. 12^2 = 144

So 64 and 144 is the answer.

The data set below has an outlier.2, 10, 10, 11, 11, 12, 12, 12, 13, 14, 14

Which value is changed the most by removing the outlier?

A: the range
B: the median
C: the lower quartile
D: the interquartile range

Answers

Data set: 2, 10, 10, 11, 11, 12, 12, 12, 13, 14, 14

range: 14 - 2 = 12
median: 12
lower quartile = 10
interquartile range = 4

Data set w/o outlier 2: 10, 10, 11, 11, 12, 12, 12, 13, 14, 14

range: 14 - 10 = 4
median: 12
lower quartile: 10.5
interquartile range = 3.5

The value that change the most by removing the outlier is A.) THE RANGE.

To answer the problem above, we must define what an outlier is. An outlier is a number in a set of data that is smaller or larger than the rest of the data. In this problem, the outlier is 2. To know which value changed the most we solve each with and without the outlier.
A. range: 12(with), 4(without)
B. median: 12 (with), 12 (without)
C. lower quartile: 10.5(with), 11(without)
D. interquartile range: 2(with), 2(without)

The answer is A. range.
