The data exercise
Collecting data
. Make kids to collect data i.e. data about his friends his habits, name, gender etc. or make kids to rate that friend. (It will help to create the model)
Data Entry
· In this process kids enter data in excel as a challenge.
Visualization
o Output visualizations
· Distribution of ratings (classes 1-5)
· On completing this exercise, they can try plotting this data using a bar, pie charts and make inferences.
Model building
· Based on what information is seen from the above visualization exercise, they need to decide which of the three features would best predict friendship. We suggest picking a feature which is a clear differentiator, i.e. those features which have more than a 60-40 split among the friend's category. If no feature is clearly able to differentiate, we suggest that anyone feature is picked while explaining to the kid the consequence of picking such a feature.
· On picking a feature and the differentiating value of the feature (say, the visualizations revealed that 80% of the friends were males, our feature of interest is Gender and the feature value is Male), the idea is to assign a score of 5 in case that feature value exists for an entry in the data that's been entered into the excel.
Validation
· Set up the atmosphere as though magic were to follow :)
· Make Table which gives the accuracy of the test and training set.
See you in the next blog.
