1.	What is a variable? Distinguish between a discrete and a continuous variable.
Answer» Answer :A variable refers to that quantity which is subject to change and which can be measured by some unit. The principle difference between a DISCRETE and a continuous variable is that while discrete variable assumes values in complete numbers LIKE 2,4,6 and 8, continuous variable assumes values in FRACTIONS like 2-4, 4-6 and 6-8 or values in some RANGE like 2-4, 4-6, ETC.]
