Use the data below to find the mean, median and mode.
28, 30, 30, 31, 32, 33, 34, 35, 37, 38, 39, 41
Can you help me to find the median?
Oh, thank you
You're welcome.
WHAT IS THE MEAN 28, 30, 30, 32, 33, 34, 35, 37, 38, 39, 41
It's the number in the middle (between the 6th and 7th).
So the median have two numbers: 33 and 34?
No. The number between 33 and 34 is 33.5.
Certainly! To find the median of a set of data, follow these steps:
1. Start by arranging the data in ascending order: 28, 30, 30, 31, 32, 33, 34, 35, 37, 38, 39, 41
2. Determine the middle value(s) of the data set. In this case, we have 12 numbers, so there is no single middle number. Instead, we find the average of the middle two numbers.
3. In this case, the middle two numbers are 33 and 34. So, we take their average: (33 + 34) / 2 = 33.5.
Therefore, the median of the given data set is 33.5.
Now, let's move on to finding the mean.
