Thank you Prashna :)
You're welcome Sophia!
Thank you so much ma'am ❤
Most welcome!
very helpful video .
Glad it was helpful!
. The other past paper I did used the formula for variance by subtracting the mean squared.. can someone explain
In 2.a, just literally substitute the values given. It was that easy, why complicate simple sums
You need to break it down in order to get 'n'.
may be you haven't gone through the "ms"... it is the requirement to show that part of the working.
