Are you Terence? That's what I hope to do eventually with this blog - to put in some things that you all can read either to revise or to add on to what you are taught in class
What's upper class boundary? What's cress seedling? Other than that, its okay to me but there's some slides I don't understand. But, IF i do get sick like last year ( one whole week ) I wouldn't have to worry about mising lessons. =]
chengchin: What's upper class boundary? What's cress seedling? In cummulative frequency table, you are often given the value of x in range form, such as 0< x≤ 20, 55< x ≤ 60 or 100< x <102 But when plotting the graph based on these values, which value do you take? u can't possible write the value as 0 < x ≤ 20, 20 ≤ x ≤ 40, and so on for each x-axis values right? So this is what upper class boundary for, taking the greatest value of x if it is in range form. Eg 0< x≤ 20 UCB is 20, 55< x ≤ 60 UCB is 60, take note that 100 < x <102 UCB is 101 It makes sense for Cummulative frequency to plot againts UCB, study the graph and u will find out. What's cress seedling? Cress is a plant, so cress seedling means the height of the young plants.

Thanks to this even when in class i miss out something also never mind le. I can study back from here.
