61. Match the following
List-I (Phases of decision making process)
List-II (Explanation)
a. Intelligence
1. Inventing, developing, and analyzing possible courses of action. This involves processes to understand the problem, to generate solutions, and to test solutions for feasibility.
b. Design
2. Selecting an alternative or course of action from those available. A choice is made and implemented.
c. Choice
3. Searching the environment for conditions calling for decisions. Data inputs are obtained, processed, and examined for clues that may identify problems or opportunities.

66. Correlation means
67. MIS can be used in controlling
68. Which of the following statements are correct?
1. Correlation analysis helps in determining the relationship between two or more variables. It does not tell us anything about the cause and effect relationship.
2. The ratio of explained variation to the total variation is called the coefficient of correlation.
3. Pearsonian coefficient always assumes linear relationship, and is unduly effected by the extreme items.
