Solution : -

(i) Where arrangement is normally utilized when the reliant variable is paired or with just to status like , Yes (or) no, genuine (or) false, 1 or 0. Real for forseeing esteems , similar to which division

of popular.

(ii) To the extent recollect that , class we got presented to just arrangement tree till now. I'll base by discourse just restricting to order tree.

As Rajesh sir specially (or) additionally specified in our class , that CART is ordinary perfect for pretty much adjusted informational index and further more made reference to there isn't hurt in utilizing it for sketched data set.

Why do we use standard deviation and not mean to measure the EEG signal? Select one: a. Because the standard deviation is easier to measure. b. Because the standard deviation is less affected by outliers than the mean. c. Because the standard deviation measures variability and brain signals are more variable than other physiological signals. d. Because the standard deviation is a better approximation of the mean value of any data.
