*1 June 2022*#### 2.5 Exponential Models

The exponential function is set apart from other families of functions because of the fundamental impact of having the variable in the exponent. It stops being a multiplier and starts being more 'powerful' (forgive the bad joke). These functions...

*1 June 2022*#### 4.4 Bivariate data & Linear Correlation

This topic is all about looking for relationships between variables. Does life expectancy depend on GDP? By collecting 2 variables about the things we survey we can use scatter graphs to represent the data and then look for correlation and...

*5 May 2022*#### 1.6 Accuracy and Estimation

Accuracy and Estimation 1.6 When numbers are reported in the news, or as statistical results, they are either displayed exactly, or they are rounded to a certain degree of accuracy. Understanding how and when to do this can give us a deeper...

*2 May 2022*#### 1.4 & 1.7 Compound Interest, Loans and Annuities
