Kumusta everyone!
Welcome back to my blog. I apologise if I haven't pot any blogs yet, but here you go. Today's blog is going to be about Mean, Median, Mode and Range. This is going to be a long blog.
Last two week, we have to race in a 50m but we have to do it twice, after we run twice in 50m we also have to run 100m 2 times also.
Last two week, Maths, we need 5 members in our groups. My groups are Lhysette, Rheanne, Jaren and Cate.
What we have to do is to figure out what is the, Mean, Median, Mode and Range by using the time that we run.
I know your confused and doesn't know what I'm talking about. But you will understand when I started explaining it.
The first think we did is to share each other number.
Here's our time when we were running:
50m :
Jaren:7.35 and 7.21
Jhrnylle: 7.46 7.33
Lhysette: 7.30 and 7.21
Rheanne: 7.16 and 7.14
Cate: 8.0 and 7.0
100m:
Jaren: 18.22 and 20.12
Jhrnylle: 19.27 and 20.21
Lhysette: 18.2 and 20.30
Rheanne: 7.33 and 18.3
Cate: 18.30 and 20.84
I'm going to tell you what Mean, Median, Mode and Range means.
Mean: Count how many numbers are there, keep that number for later. Add all the numbers together. Divide it with the number you keep earlier, and what number will it shows is the answer.
Median: Order the number from smallest to biggest, find the middle number, and the middle number is the answer.
Mode: The number that appears the most is right answer, Mode can have more than one answers.
Range: Reorder the number to smallest and largest. Take the smallest number and the biggest number like this:
Smallest number: 2
Biggest number: 9
9 - 2 = 7
Answer: 7
Take them away and that is the answer.
Lets begin now!
Answers:
Median, SPORT 1, 1: Median, SPORT 1, 2:
7,7,7,7,8 = 7 7,7,7,7,7 = 7
Mode, SPORT 1, 1 Mode, SPORT 1, 2:
7,7,7,7,8 = 7 7,7,7,7,7 = 7
Mean, SPORT 1, 1 Mean, SPORT 1, 2
7,7,7,7,8 = 36 7,7,7,7,7 = 35
➗ 5 ➗ 5
------------ ----------
7.2 7
Range, SPORT, 1,1 Range, SPORT, 1, 2
7,7,7,7,8 = 1 7,7,7,7,7 = 0
Median, SPORT 2, 1: Median, SPORT 2, 2:
17,18,18,18,19 = 18 18,20,20,20,20 = 20
Mode, SPORT 2, 1 Mode, SPORT 2, 2:
17,18,18,18,19 = 18 18,20,20,20,20 = 20
Mean, SPORT 2, 1 Mean, SPORT 2, 2
7,19,18,18,18 = 80 18, 20, 20, 20, 20 = 95
➗ 6 ➗ 5
---------- ----------
16 19.6
Range, SPORT, 2,1 Range, SPORT, 2, 2
17,18,18,18,19 = 12 18, 20, 20, 20, 20 = 2
How did we figure out the answer?
We use the start of our number. For example, my I run 19.7 we use the number "19" for the start.
Thank you for reading my blog I hope you learn something new today. Please give me some helpful, thoughtful and positive feedback. I will see you all in my next post! Bye!
