hey people.
sighs. today there was like tonnes of stress. its like sigh. when u have 2h20mins of math lessons how'd you feel? stressed..right? i mean like hello.....mrs toh comes in doing a new topic of differentiation, ie. Product of a function and then after that mr chng comes in scolding us because some idiots didnt do their work well and then goes through the rate of change worksheet and then its like whoa like that. i mean how much more tired can you get?? sigh. anyways.
i just picked my peer tutie for chem, her name's JUNE! yays. [claps hands]. now its gonna be easy lahs. june's chem is quite good right? haha. so yeahs. EASY LARHS! haha. how long was it ago since i used ACTUAL singlish? okays not long right? hahaha. anyways.... tomorrow is the E Math Common Test and i just looked through and tried studying in school on the whole statistics topic and i think i'm gonna flunk it. real bad. i cant remember hot to do lahs. okays since i've got so much space, let me try reciting them here.
mean: average
median: middle term
mode: most frequent.
to find frequency density, take frequency divide by the difference in terms. for example, frequency is 80, range:[10
Upper Quartile: 75% of graph. (Q3)
Lower Quartile: 25% of graph. (Q1)
Interquartile range: Q3-Q1=Q2. this = 50%
Cumulative freqency graph should end with the TOTAL AMOUNT of a certain term.
Remember, if the question requires you to find the higher score between 2 papers of exams, find the MEDIAN of all terms, read the marks then see which scored higher.
If the question asks you to find how much a person who scored 50 marks for paper 1, find paper 2, u trace up 50 marks to the curve where it cuts, trace it to the x axis then back down to the y axis and read the answer.
if the question asks you how to find the average of all goals scored in the soccer matches, you take all the TOTAL number of goals scored divided by the TOTAL number of games played. yeahs.
i think thats like all, i swear there's some stuff wrong in there, but sigh. i dont know lahs. whatever. i tried already. put in effort already, so thats that. tomorrow is xenia's birthday. so wana wish her a happy birthday in advance and May God Bless you this one year that you're 16!
okays. thats all i have and i'm gonna end off, tomorrow or the day after that i'll blog about the crazy tests next week and my opinions on "certain matters" keep watching this space for more information and the juicy thoughts. [at least what i think it would be (((:]
much love!!
every life is a new experience
