Two more days to QAS exam...sian ah... why did i feel sian? Well, it's because i have been trying several past year exam for paper for this module, the questions set are so repetitive, it's no wonder that i will feel sian after trying for so many papers. Just like questions on Cumulative Frequency, this will sure come out in Section B short question. the question usually give a whole chunk of data, you will need to sort out the data according to their class,so you will have to decide your own class width annd class interval. then construct a frequency distribution table. Then count the frequency in each class (the most heachache part,cannot be distracted or else lose count!) then, plot frequency polygon or ogive curve,depending what the question ask you to plot...For hypothesis testing, as usual, write a pair of hypothesis statements, then calculate test statistics(z or t,depending on the sample size), look up the table and then make conclusion(accept or reject Ho)

the anova(analysis of variance) question is the most tedious one. As usual, write at least 2 pairs of hypothesis statements,depending if the question says assuming no interaction or not. next is the killer part,which is computing the sum of squares(SS). for 2 way Anova, we have to compute SS of both factors,both arranged in columns and rows,thus SS(rows) and SS(column). If you have seen the formulae for calculating the SS values for columns and rows, you will know why it's so tedious. For SS(total), it's even more killer..this involves summation of the squares of every individual data..imagine u have to square 50 datas....sianz...then construct Anova table(5 standard columns: source of variation, deg of freedom,SS,mean square(MS) and F ratio)...next, look up F table to compare F ratio and then finally make conclusion. this is similar to the hypothesis testing questions.

Anyway i have at least 90% confidence of doing well for this module because i have done well for the 2 quizzes..haha....after QAS paper, i will focus on practising for my English oral exam which will fall on 24th august..12more days to EL oral exam...Please pray for me. thanks a lot. Got to go now,shall blog more next time. Bye!
