shorter than TT Air‚ it does not significantly affect the output as the one day does not change much (unless there had been a market shock). However based on Central Limit Theorem‚ if the sample size is greater than or equal to 30 samples‚ the sample statistics reflect the time population parameters. • The Median data does not show much in this case as the range (4.7 AA Fly and 6.8 TT Air) is small for both AA Fly and TT Air. This means that the mean is more applicable to be used. • The Mode of AA

Maze PowerPoint Project Guidelines 1. Your maze must consist of between 20 and 25 slides. You need to have a clear beginning and ending. Therefore‚ you need a title slide‚ as well as a conclusion slide. 2. For your maze‚ you should consider your audience (classmates)‚ the message you are trying to get across (why are you sharing this information?)‚ and the setting for your presentation (Room 612). 3. Your maze can be about anything‚ but must be appropriate for viewing in the classroom! No drugs

RESEARCH METHODOLOGY LESSON 20: PRINCIPLE OF HYPOTHESIS TESTING So far we have talked about estimating a confidence interval along with the probability (the confidence level) that the true population statistic lies within this interval under repeated sampling. We now examine the principles of statistical inference to hypotheses testing. By the end of this chapter you should be able to • Understand what is hypothesis testing • Examine issues relating to the determination of level of How is this

Prezi vs Powerpoint Over the years‚ PowerPoint has been the easiest weapon of choice for presentations. Its availability and ease of use makes it the most popular presentation tool in history. Some years ago‚ a web-based tool for presentation was created to provide users with a different option for presenting a concept or idea. This tool is called Prezi. The popularity of Prezi can be pointed out to its visually attractive and refreshing effects. Nevertheless‚ it is important to note that both presentation

Mental Mathematics is the ability to utilise mathematical skills to solve problems mentally. The marks scored by pupils generate statistics which are used by teachers to analyse a student’s performance and development of theories to explain the differences in performance.
