Scintillating Statistics! And two important reminders...

A bit of an adventure across the road this morning for Year 12... The lesson was spent thinking about statistics - and specifically measures of central tendency.

You need to understand:
- mean, mode and median
- standard deviation
- range and interquartile range
- box-and-whisker plots

You will not be asked to calculate things like standard deviation or Spearman Rank from scratch in an exam, and nor are you expected to learn the formulae. You may, however, be given a partially completed calculation to work with, and it is important that you understand a) how the calculations work, and b) why they are useful from a geography point-of-view.

Remember that you have the "skills checklist" from the specification in the handbook I gave you at the beginning of the year.

Assessment Week
Please don't forget that next week is Year 12 Assessment Week, and so in your lesson on Monday you will be completing an exam question - under exam conditions. As it is not too long until your Unit 2 exam (12th January), we have decided that the most useful thing would be for you to do a skills-based paper. Your exam in January will be skills-based, but will use content from either the Population unit or the Rivers unit, and then there will be generic fieldwork questions. The paper you do on Monday will have some Rivers and some Population questions (skills-based) and some generic fieldwork questions.

Need to be finished for Monday if they are not already!!
