Measures of Central Tendency (Grouped Data) | Basic Statistics

The simplest explanation on how to find the mean, median, and mode of a grouped data.

[@kinsashanakamura1705]

When i calculated for the mode i got the answer of 19.65 not 20.38

[@PinoyMathematician]

Sorry wrong calculation. Im not sure how I got that 20.38. :(

[@kinsashanakamura1705]

No worries the procedures and formula are correct though nice video btw

Im sad for comitting this mistake. Thanks for ur appreciation.

i dont know, if measure of central tendency worksheet but without frequency. I want put class size and frequency. How to make construct a frequency table. you m use any appropriate class size and interval?

[@PinoyMathematician]

For constructing frequency table, usually the class size is given in the instruction. But if it's not given, then you use the formula i = Range / k where k = 1 + 3.322logN

[@mainamburu8036]

When taking the lower class boundary for median or mode are we supposed to subtract .5 from the lower class boundary or just you take that lower class boundary as itself without subrtracing .5

[@PinoyMathematician]

You have to subtract. It is not lower class boundary if you dont subtract .5, it is only lower limit.

[@mainamburu8036]

@@PinoyMathematician I see some people here on you tube taking the class limit as it is without subrtracing .5 soo I was just confused

I dont know why they do that. I believe it would give incorrect answer.

Sirr can i ask if were going to find the lcb u need to subtract it to .5 is it only .5. Or theres other else

If the given are whole numbers, it's 0.5, but if there's a given number with one decimal place, then it's 0.05, and so on...

[@naaadoleymooley6943]

@@PinoyMathematician i its still not clear where the 0.5 is coming from

[@PinoyMathematician]

It’s always 0.5. As long as the values in the intervals (upper and lower limit) are whole numbers.

why is the median class different from your modal class which is your highlighted median is 15.5 and your highlighted mode is 18.5... I hope you notice me

Di po kinukuha yun, kumbaga fixed po siya, always na 0.5 ang i miminus pag lower class boundary and pag upper class boundary naman +0.5

[@MonymouAkueiAchuil]

how can l find frequency

[@PinoyMathematician]

Frequency must be given already.

[@carene939]

Why is the interval of the median is 3 when the interval of 10-12 is only 2

[@PinoyMathematician]

10-12 is 3. That is; 10, 11, and 12

[@BrendonR.B]

For the lower class we should just take the 1st number class in that row, my lecture gave me wrong for using another LCB

[@saodah1541]

why did you choose to minus 0.5

That's fixed for a given that is not decimal.

sa mode po, paano po kapag nasa pinakangbaba yung highest frequency? pano po makukuha yung d2?

consider zero lang yung frequency sa baba.

Good day po, Sir. Consider as correct pa rin po kaya kung magkaiba yung naging answer sa mean ng group at ungroup pero same data lang po ang ginamit?
