Tuesday 10 August 2010
We will continue with Exercise 4D.
Friday 6 August 2010
Exercise 4D is concerned with making predictions. Interpolation is making predictions within the bounds of the original data, extrapolation is making predictions beyond the bounds of the original data. Predictions are reliable if they were obtained using interpolation from the scatterplot, indicating reasonably strong correlation and containing a large number of points.
Exercise 4D: 2, 5, 8, 11, 14, 15, 16
Tuesday 3 August 2010
We will continue with Exercise 4C. Report writing day is this Friday and you need to have finished everything up to and including 4C to be considered "up-to-date."

For our firstnext assignment, due this Wednesday 28 July,4 August, I want attempt questions 15 to 49 of the on p. 203.203, and question 1 of the extended response questions on p.205.

Friday 30 July 2010
Exercise 4C is all about lines of best fit and reviews work that we did at the end of Chapter 3. In the second half of the exercise we cover the two-mean regression line.
Exercise 4C: 1(e)(f), 3, 5(b)(c), 7, 8, 9, 10(b), 11, 12
Wednesday 28 July 2010
We will complete Exercise 4B and work through the Chapter Review questions that I have set.

For our first assignment, due this Wednesday 28 July, I want you attempt questions 1 to 4 of the short answer questions of Chapter 4 on p. 203.

Chapter 4 continues with the correlation coefficient, which quantifies the dependence of one variable on another.

Welcome to the second semester of General Maths F.For our first assignment, due this Wednesday 28 July, I want you attempt questions 1 to use this Wiki as a resource. I will be putting up4 of the exercises that you need to complete, links to websites that may help you revise for SACs and exams and opening a Discussion page which will give you the opportunity to contact me outshort answer questions of school hours and let me know if you are having any particular difficulties.Chapter 4 on p. 203.

Today we begin Chapter 4, Bivariate Data. This is where we investigate the relationship between two variables - does one variable depend on the other and, if so, how much?

We will be doing the last exercise of Chapter 1, "Comparing sets of data". We will be seeing a pretty cool application of the TI-Nspire that gives us all the answers, but your main task will be interpreting the data, i.e. you will have to think about your answers rather that just depending on formulas!

In this class, I will be going over the standard deviation work again, and working through how to use the TI-Nspire for calculating means, medians, standard deviations etc.

Boxplots are another way to represent data: they show lowest score (Xmin), lower quartile (Q1), median (Q2), upper quartile (Q3), greatest score (Xmax).

Stem-and-leaf plots come as a bit of a relief after all of that mucking around with ogives and cumulative distribution plots.
