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.
task is to move all the reds from the left to the right and all the blacks from the right to the left. The middlebox is empty to allow moves.
The moves follow strict rules.
Rule # 1: the reds can only move to the right and the blacks can only move to the left. No backward moves are allowed
Rule # 2: Equally applicable to the black and the reds, each dot can only move one step forward in the box in front of it is empty, and can skip the contiguous box is occupied by a different colored dot to the following box if empty.
While moving your pieces, carefully record all the moves you made. Start first with the 5-boxes set, then the 7-boxes set
Try the same rules for a 9-boxes set and then for an 11-boxes set. Record all your moves on paper
Examine all four cases and find a pattern that relates the number of moves to the number of dots. Explain how you arrived at this conclusion
Create a general formula that will give the number of moves based on the number of dots regardless of how many dots you have.
