thank you! it really helped!
very good video, and love your sweater😅
Thanks
is there a video made for linear combination of random variables in alevel statistics ??
That would be in Further Maths and I haven't got that far yet.
Is the mean affected by division and subtraction too?
Is standard deviation affected by division too?
The a can be negative and the b can be a fraction, so yes.
Jack Brown ok thanks!
Jack Brown What affects the median and the mode?
They would both be affected by addition, subtraction, multiplication and division.
For example:
2, 3, 3, 3, 3, 4, 5
median = 3, mode = 3
If you have a linear transformation of 2x+3 then you get:
7, 9, 9, 9, 9, 11, 13
median = 9, mode = 9
Jack Brown thanks.
Is this part of the aqa spec because I haven't come across this before?
yh same
@@stormydoctor9009 It IS in the AQA approved Oxford textbook as "Coding", although it is not specifically mentioned in the specification.

hi jack what affects q1 and q3
What do you mean by q1 and q3? The lower and upper quartiles?
@@TLMaths yeh
is this for OCR MEI too?
Linear coding is not specifically mentioned in the specification, but it could be part of problem solving associated with the question, so I wouldn't completely discount it.
is this in stats or pure ?
stats
can we have CIE things please sir, your faithful student
Is this in CIE?
