Interpolation

A Level Maths revision tutorial video.

[barbarianking]

this explains this so much better than the new Year 1 Statistics A level textbook. Amazing. Thank you

[lmaoannie]

Spent hours trying to find a video that explains this well and doesn't over complicate everything. Thanks so much :)))

This is actually very easy! Our teacher taught us some kind of a diagram for it which I could never remember, this solution is so much easier! Thank you, I've actually got a chance in tomorrows exam!

[shyamparmar]

U are an absolute legend, saved me for my stats test tomorrow

[annakalmykova]

I never ever understood it with whichever teachers I talked to, but now I do, thank you !!!!

[eyeneneb.]

Thank you for this video. 3 years later and it's still very good.

I’ve been stuck on this for days. THANK YOU!

at 6:13 it would not be the 55th value because to find the median you need to do 110 + 1 and then divide by 2, because 55 is not the middle value of 1-110.


Think about it what is the median of these numbers: 1, 2, 3, 4, 5.
You dont do 5 / 2 which is 2.5 because you can clearly see that 3 is the middle number


therefore what you would do is 5+1 =6 then divide by 2 to get the median which in this case would be 3.

sir how do you calculate percentiles using linear interpolation?

[jamescandfield]

For a histogram how could you estimate the number of something more than a certain speed ? or time etc

[sea]

Such a well explained video, thanks a lot!

[reidwan]

When do you add 1 when working out which number value you want for Q1, Q2 etc..

[jackyye]

How would you calculate the nth percentile?

[acewolfftw]

You have helped me more than you will ever know

[possiblyunmatched]

can we simply use this, method if the question mentions to use linear interpolation or would we have to use that weird diagram that looks like a switch in physics method?

[syedsalehnasir]

THANKS ALOTT SIRR, BTW do you have the entire As and A Level syllabus including Statistics on this channel?

[misan]

What would i do it asked to find how many days(an example) are one standard deviation above the mean? How woukdninwork it out with interpolation

Hi, Thank you for this informative video. It is genuinely helpful. However, I needed to ask you if it is possible to sum the cumulative frequency percentage of two different data sets with the same intervals. For example, if we wish to measure the fixed (0-4 possible)responses of two different questions from the same number of participants. Can we measure cumf percentage for each separately and then add those percentages together? Looking forward to hearing from you.

God sent you to me, I owe you my marks, thank

What if the cumulative frequency was odd?
