Cumin is the ground dried seed of the cumin plant which is a member of the parsley family. Turmeric is the ground dried rhizome of the turmeric plant which is in the ginger family. So they are very different and they have different flavors. Turmeric though it does have flavor is used as much for its bright golden yellow to orange color.
Population Distribution Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people. Sparsely populated places tend to be difficult places to live.
A normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme.
