Be careful as they may also write it as: σ (lower case “sigma”) for population standard deviation σ2 is the symbol for the population variance. s2 is the symbol for the sample variance.

27B)IV) It is a Z-score question.

Ok, I have just had an idea. How about at the time of the HSC many factors such as Physical, emotional,etc affects one's body image. From there you could also link to media articles, peer pressure and other contributing factors as per from the syllabus. That way you are at least eliminating the...

Have you tried looking at some of these: http://community.boredofstudies.org/showthread.php?t=51072

I can't entirely remember what I wrote but I ended up doing an IRP on Bullying in the Workplace and how it affects an individual's wellbeing.

I personally think the top one would allow for more scope. You could perhaps do a comparison between older FB users in the survey as well to get a better sample and indication of the contributing factors. And if you don't know any older FB users you could always create a survey through survey...

Use excel and split it up into proposed and actual times in a Gantt chart. Also use different colours where possible and have a key. There are heaps of online tutorials by Microsoft that go step by step if you are not IT inclined. Otherwise you could perhaps use a diary and keep a record that...

+1, that is the only way I know of learning it. You can also subtract the powers when you write in scientific notation and look at the jumps to figure out how many zero's if that's easier. Other than that, I guess practice is the key! :)

http://www.boredofstudies.org/view.php?course=35 http://hsc.csu.edu.au/cafs/ The Excel and Leading Edge textbooks are also good for this section of the syllabus. :)

Unfortunately, I think they are the only ones around. In an old thread by Sam D and an actual IPT teacher- they may have given reference to another (although it would be a rare find if you could locate that thread). Otherwise the two you mentioned above is what I used and just went over the...

press mode 2 to get into stat mode 1 to get Var enter scores pressing = after each one press AC once done press shift press 1 press 4 to get Var select 3 or 4 based on the standard deviation you are calculating.

As for your question from the 2007 paper there is a formula you could use: (n+1)*P/100 Where n is your number of scores and P is in this case 40 as you want the 4th decile. There is another method-- of dividing the graph once again that most maths general maths books use from memory.

Oops... was doing some harder maths in the morning. Perhaps I had completed too much- you are right! :) Sorry for any confusion caused! Question 21: Data collection and sampling (I think it is a prelim topic).

Question 21: Total = original number tagged x total recaptured ÷ number tagged on recapture Question 9: Yes you use the line. Hard to show here but you use the cumulative frequency axis to segment and draw the line down to the corresponding score. (Plus this question only asked for a rough...

Question 9: Q3-Q1= 65.5-35.5=30 The IQR is the difference between Q3 and Q1 Q1 and Q3 is determined by the 1/4 and the 3/4 point in the data. Just as a side note Q2 is 55.5 Question 13: You need this formula: yield=dividend/(market price)×100% (I don't think the formula sheet...

I have been good. However, just a bit busy with uni at the moment as midsemester exams are slowly approaching. So how have things been for you?

Fair enough! :) I would say a double entendre as it has a dual meaning of Frankie literally kicking a mine and man walking upon the moon. Furthermore a double entendre is common in Shakespeare, poems and music.

From a linguistics perspective: p- Bilabial voiceless stop and plosive are the correct terms depending upon where the letters fall. s- Alveolar voiceless fricative and sibilance are the correct terms depending upon where the letters fall. m- Bilabial Nasal. Also I have heard it called a condring...
