Hey there, welcome to numerade.
00:04
Let's say we are recording the resting heart rate of five of your classmates.
00:09
We are asked to find a mean, median, mode, and midrange.
00:14
So let's start by writing our mean.
00:17
We're going to be rounded to one decimal place, and be sure to include the unit for pulse bpm.
00:25
So therefore, our mean here will equal the sum of all of these heart rate.
00:36
Bpm divided by our sample size n so if we sum of all the values here we'll get a sum of around 343 divided by the sample size which is 5 hence we get a mean that is around 68 .6 bpm okay now let's find the median so for our median we know it is basically the middle value so our median value is basically our middle value.
01:26
And we can clearly see that the middle value here, when we rearrange the data from least to greatest, will be a value that equals 69 .0.
01:43
And then we have our mode, which basically represents the value or number that appears the most in the data, set.
01:59
So if we again look at the dataset, our mode, we do not have a mode.
02:07
Because all the values here repeats one.
02:10
So it will be 66, 67, 70, and 71, and 69 are all considered as the mode...
