TIPSAND STRATEGIESThe Matrix formation method leaves very little room for error.

However, if the number of parameters is high, this method may

become very tedious and so this method is best used for sets which

dont have too many parameters.

The Consolidated table method uses a much smaller table. The

chances of making a mistake is higher as the options need re-

reading to arrive to a conclusion but this method is more convenient

for question sets having many parameters.
