2:19 is there no easier way to find the median? I remember theres a formula and this way just feels so lengthy and complicated (thats what i personally think)
There is if you check my grouped tables video. I just teach this one here because on foundation the total frequency is usually very low. Typically foundation students find this approach easier.
2:49 Wrong :( You might as well ignore the frequency table, then… You are relying on categorical data - like male vs. female, for example - but it just so happens to have numbers as part of those categories.
Omg 3:01 of the vid makes so much sense i was never explained how to do the averages in this type of question and now i know im so happy haha
Amazing! I try my best to explain what is going on rather than just learning "tricks".
Thank you so so much it was really good and helpful
Thank you

Do we add the 1 to 79 in the shoe size question for median to make it even ?
We add one to locate the median in general. If there are 5 items the median is in the 3rd position (5+1)/2
If the median is not a whole number, then what do we do? For example 2.5 after the 1 is added.
Do we choose 2nd or 3rd position please?
Very good
Good
Thanks
i dont see why we add 1
I think because of the running average but not sure. It doesn’t matter if u know thought so don’t stress about it
Just add it this is a method

Not really sure what you're on about. At 2:49 I explain that some students make common errors and explain such errors.
