Answer:
1) 22
2) 19.5
3) 26
4) 12
5) False
6) True
7) Mean
8) False
9) Add all the numbers and divide by the total number of numbers
10) Bimodal
Step-by-step explanation:
1)Use the data to calculate the mean. 24, 31, 12, 38, 12, 15 *
To calculate mean you add all the numbers up and divide by the total number of numbers.
![\frac{24 + 31+12+38+12+15}{6} = 22](https://tex.z-dn.net/?f=%5Cfrac%7B24%20%2B%2031%2B12%2B38%2B12%2B15%7D%7B6%7D%20%3D%2022)
2) Use the data to calculate the median. 24, 31, 12, 38, 12, 15 *
For median, arrange the numbers from lowest to largest
12, 12, 15, 24, 31, 38
use (n+1) / 2 to figure out which value is the median
(6+1) / 2 = 3.5 (median is in between the 3rd and 4th value)
(15+24) / 2 = 19.5
3) Use the data to calculate the range. 24, 31, 12, 38, 12, 15 *
Range is max value - min value
38 is max and 12 is min
38 - 12 = 26
4) Use the data to calculate the mode. 24, 31, 12, 38, 12, 15 *
Mode is the value that appears most frequently
In this case 12 appears 2 times, therefore it is the mode
5) the mode represents the number that appears the least *
False, mode is the number that appears the <em><u>most</u></em>
6) To calculate the range we use the highest and lowest number ? *
<em><u>True</u></em>
<em><u></u></em>
7) Average is another word for *
<em><u>mean</u></em>
<em><u></u></em>
8) the range indicates the middle number ? *
<em><u>False, </u></em>range is the max value - min value
9) which statement best describes the mean. *
<em><u>add all the numbers and divide by the total number of numbers</u></em>
10) A data set with two modes is known as *
<em><u>bimodal</u></em>
