They say statistics, statistics and lies: we can convey information in different forms using statistics and this is a powerful tool. Understanding statistics is more important, knowing the relevance of the information given.
Prior Knowledge & Skills
Numeracy and mathematical operations including squares and square roots is important. In statistics we need to work with large data sets therefore being able to lay out information in tables is a required skill. Having an understanding of life is also important in order to take on board the significance of statistical data, so maturity plays its part. Skill with 2D shape and coordinates makes the absorption of statistical data easier.
Starting with averages in the forms of mean, median and mode is normal. Understanding range and the spread of information helps us with the concept of standard deviation. Selection of the best graphical representation for statistical data enables a deeper understanding of the data. The objective is for the user to be able to create persuasive argument using their statistical calculations.
