4. Plot the data over 5 year intervals eg. 19831987,19881992,19931997,1998 2002, 2003 - 2008, averaging our the values over the period. 5. Identify any outliers in the data. If any are found, apply appropriate transformation to the dataset. 6. Create a Linear Regression Model for the different variables. Identify the following: (a) sample minimum (smallest observation), (b) lower quartile or first quartile (Q1). (c) median (the middle value), (d) upper quartile or third quartile (Q3), (e) sample maximum (largest observation). 7. Give the linear regression model equation from the data for the different variables
