ution, regression, decision trees
Past paper has 5 questions (attached), we will have 4. Complexity of questions will be reduced slightly for decision trees and regression.
Visualisation question – written in word file or hand-written and scanned or photographed.
Sketch using online normal distribution visualisation applet (add notes around this to discuss if necessary) or sketch by hand and scan or photograph.
For mathematical workings, use formulae sheet, copy, paste and adapt, or scan / photograph your workings and upload.
Decision tree – use Office smart shapes, or sketch by hand and scan or photograph. If formulae are required, then use formula sheet, copy, paste and adapt.
Regression – written in word file or hand-written and scanned or photographed.
MCDA – written in word file or hand-written and scanned or photographed.
Remember if they appear, decision trees and regression will be a little less technical than they have been in the past. (To allow more of a buffer with regards to time available to complete and upload).
Visualisation and MCDA questions will be more general (strengths and weaknesses, key messages, make some recommendations).
Exam questions will be set so as to minimise practical and logistical difficulties in uploading answers.
Question 1 options:
It has an approximately normal distribution with approximately the same mean as the population.
It has the same shape and mean as the population.
It has an approximately normal distribution with a different mean as the population.
