To find the median, order the numbers in the data set from least to greatest (or greatest to least, either one works) and then find the number in the middle. If there are 2 numbers in the middle, find their mean.
Step 2: Find the median (middle number). The median is the number in the center. Count in from each side equally to find the middle number. 76, 78, 82, 84, 88, 90, 92, 94, 98, <span>100 </span>78, 82, 84, 88, 90, 92, 94, 98 82, 84, 88, 90, 92, 94 84, 88, 90, 92 88, 90 88 and 90 are the middle numbers. Since there are 2 numbers in the middle, we must find their mean.
Step 3: Find the mean of the 2 middle numbers. Mean is also known as average. To find this, add up the numbers and then divide by the amount of numbers there are. In this case, that means adding 88 and 90 then dividing their sum by 2. This can be represented by the equation (88 + 90) ÷ 2. 88 + 90 = 178 178 ÷ 2 = 89 89 is the final answer, it is the median.
A plane from Córdoba bound for Estados Unidos and makes stops in Chile and Bolivia. The plane has a capacity for 507 passengers. He leaves the Córdoba airport with 119 empty seats. In Chile 33 passengers go down and 121 go up. In Bolivia 129 go down and 39 go up. How many arrive in Estados Unidos?
- The plane has capacity for 507 passengers.
- 119 seats are empty when it leaves Córdoba.
Meaning that there were (507 - 119) passengers on board = 388 passengers
they can each sit on floor by lining equally some can move back for example the shortest ones can sit medium tall can stand and the largest people can stand in the very back
