Distance Education Assignment for submission second semester/Module II Mathematicsfor Instruction I : Write "True" if the statement is correct or "False" if the statement is incorrect on the space provided. 1. The mid-point of a class which is also called a class mark is half way between the lower and upper limits. 2. Dispersion describes the degree of variation in the data. 3. A basic feasible solution is a solution to a linear programming problem that corresponds to a corner point of the feasible region. 4. Mean deviation about a mean and mean deviation about median cannot be equal. 5. In the proportion a: b = c: d, the sum of the means is equal to the sum of extrems. 6. If the first, second and third quartiles of a distribution are 7,10 and 13 respectively, then the distribution is symmetrical. 7. If a distribution is negatively skewed, then the distribution is not Symmetrical and the long tail to the right. 8. The coefficient of variation is measured in different units as the data. 9. For a positively skewed distribution mean is greater than mode. 10. Quota sampling is a probability sampling method.
