yeah it did


now only one confusion about what scales to use.

LOL good ...scales depend on the readings like if they're close to multiples of 4 then use these multiples on the axis and if they give you a short line that doesnt fill up the graph divide the multiples to 2..sorry sorta hard to explain it but try a question and it wont seem that hard while thinking about this, and just remember dont use hard scales like of 15 or 16 or 26 use easy ones.

i only heard
multiples of 1, 2, 5 and 10


so eventually 20 will also be allowed..



but sometimes, they show in examiners report, about ppl using 2.5 and 3
that confuses me



then they even show even no, while i use 5.
that also confuses me.

I went through the graph you posted and you haven't done it right, it looks like you were in a hurry apparently? Because we had to plot the distance horiztonally firstly, then look at its readings ..they sorta go like 25 29 36.2 which is alot like 25, 30, 35 but you can't start from 25 as its a multiple of 5 it must start from 5 (because if the first number is 25 then the next value is 50)and the point that is the origin it is better to keep it 0,0 , so therefore it goes like 0,5,10. Okay now thats cleared you check that this way does your final number fit in and you count till the end of the axis and he last number is 70 but our final is 50 so it fits and it is not alot of difference so its cool..and by even scale they mean like you dont wanna go 6 to 13 to 45 they mean multiples of something like from 2 to 4 to 6 and so it can even be 5.
I solved the question you can check the whole thing out, any other doubts feel free to ask

:S:S:??

this is written in examiners report

Most candidates attempted to plot an accurate line graph with the values for the surface area of the
model fruit in cm³ on the x-axis and the distance travelled/cm on the y- axis. Some candidates
used a ruled line point to point and others a line of best fit. Either of these methods was acceptable
providing that the line was accurately drawn. The scale caused problems for candidates. The
range of values for the surface area of fruit increased by 32 cm² for each set of repeated values of
distance travelled and an even scale was required. If this range started from 30 cm² (instead of
0 cm²) and used one mm square to represent 2 cm² an even scale filled the printed grid. The
vertical scale for the mean distance travelled in cms for a value of 0 or 25 to 50 cm an even scale
could be used to fill the printed grid.


by the way, nice handwriting

Gosh yes didnt think about 32 so yea then your right but isn't it much more complicated this way starting with a dif number :S I mean if you change the Y axis scale to 32 64 96 128 160 its really much better and but starting with 0 makes it easier, though i noticed you depend too much on ms, go through it but dont chnge your answer exactly according to it i mean my way is partially wrong but if i chnge axis its cool and they said it is okay if you put distance travelled on y axis not that you have to so if a question does come be sure you put the ones on the axis they ask just in case also they say you can draw the point to point method so thats answers your prev question

Thanks  ..for the compliment:D

[SGVaibhav]

is my right or wrong still?

[SGVaibhav]

waiting for reply

[Krissy]

is my right or wrong still?

Your scale for y axis distance is good but the x axis division isnt correct and if done right it should be 25 when 5 small blocks later 30 and on, but i'd prefer using 32 mltiples for surface area and 5 mltpl for distance as your 1 point shows that its 25 and 30 and sorta doesnt make sense :s So to fix your graph change the 30 value in the start to 25 as it starts your y axis and so its the same(it has to be) and continue on with it like 5 blocks later 30 then 5 blocks later 35, and in the place you wrote 50 write 35, do i make sense?

LOL okay just change your x axis scale...thats all im saying.. from the 30 start before to 25 ..then 30 35 and on
now do i make sense?

[astarmathsandchemistry]

hey guys, i wanna say good luck to alll!! and lets hope its easy
i have one question in mind...if it says draw a curve.......do we still draw jointed lines or  a normal smooth curve?? thanks in advance

yes you do
lol
understood at last
