I love how when we needed to learn something number related and we cant understand anything from the books, teachers, recording, and the web, this is where we all end up

@lifeofmiradc Год назад

Exactly 🤗

@beyikcykarylano4522 Год назад

To find Quartiles use this formulas for grouped data Q1 = n/4, Q2 = 2n/4, Q3 = 3n/4, To find Decile use this formulas for grouped data D9 = 9n/10 To find Percentiles P99 = 99n/100 where n is the sum of frequency.

Professor Organic Chemistry Tutor, thank you for an incredible introduction to Quartiles, Deciles and Percentiles using a Cumulative Relative Frequency Table. Although I have seen this material before, this is the first time that I have some understanding of how to calculate the deciles and percentiles using a cumulative relative frequency table. A basic course in Statistics would improve by overall understanding of this topic.

13:50 The 4.25th position between 9 and 11 is not the middle of 9 and 11 (ie 10), but the .25th of it which is 9.5

@gregoryopondi3652 Год назад

Yes, exactly. So what is Q1 in this case? 9.5 or 10? This is where I'm stuck.

@jayralph7165 Год назад

what the heck are you saying? it's 10 when you get the midpoint of the two values 9 and 11 by adding them up first and dividing by two you will get 10.. you didn't follow quite well

@mars7540 10 месяцев назад

@@jayralph7165 its not 10, 4.25th postion cannot be 10 since the 4.50th position is 10. For example, 3.76th, 7.23th, 4.97th, you cant just go and add up the 2 numbers and divide by 2 to get your answer. The only time where you can do that is when the position ends in a 50th so like, 3.50th, 4.50th, etc etc. The guy in the video is missing a step called interpolating which requires creating the fractional equation of the differences. Hope people can see through this mistake.

@phennyzheng5623 4 года назад

Thx for sharing. Bt wrong answer for q1 and q2. the answer for Q1 and Q3 is not just simply find the median of minimum (or maximum) value and Q2. In you calculation, location of q1 4.25 and q3 12.75 are right, but (9+11)/2=10 is not the right q1. Correct answer should be Q1=4th+(5th-4th)*0.25=9+(11-9)*0.25=9.5. Q3=12th+(13th-12th)*0.75=19+(20-19)*0.75=19.75.

On the quartiles, percentiles and deciles ,when a decimal point occurs, we incorporate linear interpolation Eg in example (16:00) 60th percentile = 60/100 (16+1)th value= 10.2th value= 10th value +0.2(11th value - 10th value) = 10 + 0.2(17 - 16) =10+ 0.2(1) = 10+0.2 =10.2 . This also applies to the rest of the examples with decimal points. We deduct the next number (11th value) to the found value (10th value) and multiply by the decimal point (0.2). 0.2(17-16)

I did a trial of finding the midpoint of the 50th and 62.5th percentile (23:13), and the result is the same, it's 56.25. So we can really estimate that 16 (the first 16) is the midpoint of the 50th and 62.5th, which is 56.25 (approximately 56). But yeah it's just an estimation.

Hello, thank you for this video. It is really supportive since it helped us to remember the formula of how to calculate quartiles, deciles, and percentiles. However, I would like to know the value of decimals when you are saying that whole number with some decimal numbers must be calculated using the midpoint between the location of the whole number and the next number to that position. I would like to know the reason why you don't care about the decimals that you got when calculating. for example, when you get 10.3th you could have used 10th + 0.3(11th-10th). I will be happy getting the feedback from you soon.

@markanthonylaranang7486 2 года назад

on your example which is 10.3th place. get the two whole numbers in terms of place involve (10th and 11th place). use the Higher value (the value of 11th place) subtracted by the Lower Value (the value of the10th place) then multiply the result by the decimal (0.3) then add the lower Value (the value of the 10th place) then you got the 10.3th place.
