how can i improve in maths quickly? i do a tleast 1 past paper daily, i get around 60-65 every time and i really want to go for 75+ within 2 months. I keep losing marks in the first half of the paper. any tips?

[@TheGCSEMathsTutor]

random guy If you are losing marks in the first half then focus on the crossover playlist I’ve put together for a week, if you are capable of picking up that many marks then you just need to refine those earlier questions and try to get them locked off as soon as possible 😁🙏🏼

[@keiraw1853]

thank you so much for this it really helped and this is such a good channel. the ony thing i have to say is the background music is a bit offputting lol its a bit ominous

[@kushbokhiriya571]

the music lowkey a vibe

[@jayzee9149]

Good video and overall a great resource...My only quibble on this video is that joining the points for a cumulative frequency graph with a curve implies that the members of each class are not evenly spread which we have to assume for the model..Straight lines are better for the use of linear interpolation within the classes..Doesn't in reality make much difference at this level but hey ho..

[@TheGCSEMathsTutor]

Haha that’s a fair point! So I guess your quibble is with the topic itself!!

[@life_asthepooh8804]

For the median in the box plot why did you add 15and 1 then divided by 2.why not add 22 and 25 then divide by 2

[@sbonganzimande6500]

Thank you soo much this was soo much help especially for revision.

[@kyrahh.t]

what do you do if the median is a decimal, due to the amount of numbers in the set of data being even????

[@TheGCSEMathsTutor]

Then write down the decimal as your answer! If you are referring to the position of the median being a decimal, then it’s inbetween those two numbers 😁

[@kyrahh.t]

@@TheGCSEMathsTutor thank you 😄

[@study-pl9mj]

hey, great video! the worksheet on your website isnt working. Do you mind fixing this.

[@therealyaseenusman]

Sir, if you draw a cumulative frequency diagram with straight lines and not with a curve, will you lose marks in an exam? Thanks for the video btw.

[@vidisha7044]

yh duh stupid

[@user-fh6lx1fb2g]

yes, it will be wrong.

[@joethemasterofswag5379]

Amazing video , thanks for the help

[@jackjackdaw5065]

How did Green’s garden centre get an offset interquartile range? If you always divide by four it would always be centred to the boxplot no?

[@taimoorkhan3502]

Hey just wanted to ask that are these questions from past papers ?

[@TheGCSEMathsTutor]

No but they are very similar! They are questions I’ve collected over the years so I forget exactly where they have all come from over time! 😁🙏🏼

[@anviparekh9845]

wait im a bit confused for the median at 5:30 because i dont get why you have to add 1 to 15. surely u would just do 15/2??

[@mayor_naratoe8802]

When finding the median you add 1 if the number is uneven. This is so you don't end up with decimals.

[@Bruhmoment-bx7yb]

can u explain 5:59 why u divided 16 by 4? and thanks for the good vid

[@user-ye2dl4ft8q]

Becuase a Quarter is 4, its like 1/4 as a fraction, so u have to work out the Quarter of 16 which is why u divide by 4

[@theglitterqueen3779]

Hello, I can’t seem to download the workbook. Whenever i press download and open file it takes me to the page i was already on.

[@TheGCSEReviser]

Hey uh, for some reason, when I try to get the workbook pdf, it doesn't work. Is there anyway you can send the pdf directly? if possible of course.

[@nadirahzaman9774]

is there piano music behind this? 😅🎉

[@shilpatel8957]

Why only add by 1 to 15 why not any other no.?Sorry I’m kinda tapped in the brain

[@waterprincess244minecraft7]

for median, u use the equation (n+1)/2 to find position of median. n is the number of items in the list for example: 1, 4, 6, 7, 8 there are 5 items in that list (5+1)/2 = 3 6 is the median because its the 3rd number in the list

[@gray8047]

do you have a video on finding mean from box plots?

at 13:00 do u plot from the midpoint or end cause I thought it was the midpoint

[@Sup7569]

U do need to put numbers when comparing box plots

[@TheGCSEMathsTutor]

Thankfully you don’t! According to mark schemes in relation to this type of question, both marks are awarded for: “A correct comparison of medians eg the median weight for Megan was greater than the median weight for Amy C1 a correct comparison of a measure of spread eg the interquartile range of weights for Megan was greater than the interquartile range of weights for Amy For the award of both marks at least one of the comparisons must be in the context of the question” There are no mention of figures needed, and never has been (and I speak as a past exam marker and moderator) The only mention of figures is in the sub notes that mentions if figures are given then “Figures must be correct” so my advice is always to leave them as it’s just an opportunity to lose marks. If you’d like to see the latest mark scheme as evidence of this, then please see question 11(b) for November 2019 paper 2 😁🙏🏼

[@Sup7569]

@@TheGCSEMathsTutor ok but if I was to put numbers would I lose a mark cuz I’ll just do it just in case cuz my teacher said u do so I’m confused

[@TheGCSEMathsTutor]

If you get the numbers perfect that’s fine! If you get a number slightly wrong but give a perfect comparison, then you would lose a mark. I guess you have to ask the question, is it worth it? Reward: gain nothing Risk: lose a mark Of course, I would always advise that you should follow your teachers lead 😁🙏🏼
