First, to find median put numbers in order so:
5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20
10 + 12= 22 divided by 2= 11, the median is 11
14
18. It is the middle number when they are listed in order.
what is the mode of the following data 18, 17, 12, 14, 8, 21, 10, 11, 19, 20, 10, 5, 17, 12, 10, 20
As there are 6 numbers, the median is half way between the middle numbers, or (7+9) / 2 = 8
To find the median of a set of numbers, you first need to arrange them in numerical order. In this case, the numbers are 10, 12, 19, 18, 12, 13, and 12. When arranged in ascending order, the numbers become 10, 12, 12, 12, 13, 18, 19. Since there are seven numbers in the set, the median is the middle number, which in this case is the fourth number, which is also 12. Therefore, the median of the given set of numbers is 12.
8. In order: 4, 6, 7, 9, 10, 12 6 data items so median is mean of middle two: median = (7+9)/2 = 8.
5,6,7,7,8,10,11,13,14,15,16,18
14
The mean will increase from 14 to 20. The median will increase from 12 to 15.
7 digits, so the median is the 4th which is 9.
There are infinitely many sets. One possible set is {10,10,12,13,15}
Whatever you like. The median value for each of the following three sets is 10. For the set {1, 9, 11, 12}. the mean is 8.25, smaller than the median. For the set {1, 9, 15, 15}. the mean is 10, the same as the median. For the set {1, 9, 15, 16}. the mean is 10.25, larger than the median.
18. It is the middle number when they are listed in order.
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
what is the mode of the following data 18, 17, 12, 14, 8, 21, 10, 11, 19, 20, 10, 5, 17, 12, 10, 20
As there are 6 numbers, the median is half way between the middle numbers, or (7+9) / 2 = 8
median means the middle score of the given no. of data in case of even no.of data arrange in ascending order(small to big) median = n\2 +(n\2 + 1) {where n = no . of data} 5th data + 6th data\2 here : 2+3+5+7+11+13+17+19+23+29\2 : 24/2 median of first 10 prime no.s is 12 in case of odd no.of data: arrange in ascending order(small to big) strike from both ends and the left out data is the median eg: 2,3,5,7,11,13,17,19,23 here: 11 is the median of the first 9 prime no.s
