89. Diagrams are tools of: (a) collection of data (b) analysis of data (c) Summarization of data (d) Presentation of data 90. Ogives are useful to locate: (a) mean (b) median (c) mode (d) weighted mean. 91. Histogram is useful to determine: (a) mean (b) median (c) mode (d) all these. 92. For open-end classification, the best measure of central tendency is: (a) AM (b) GM (c) Median (d) Mode 93. The most commonly used measure of central tendency is: (a) AM (b) Median (c) Mode (d) HM. 94. Quartiles can be determined graphically using: (a) Histogram (b) Frequency Polygon (c) Ogive (d) Pie chart. 95. The value of the middle most item when they are arranged in order of magnitude is called: (a) Quartile (b) mean (c) mode (d) median 96. The value which occurs with the maximum frequency is called: (a) median (b) mode (c) mean (d) none 97. For calculation of - - we have to construct cumulative frequency distribution. (a) mode (b) median (c) mean (d) none 98. The measure of central tendency which is based on all the observations of a series is: (a) mean (b) median (c) mode (d) deciles 99. Average is a measure of : (a) central tendency (b) dispersion (c) symmetry (d) concentration 100. To find median, arrange the data in : (a)ascending order (b) descending order (c) ascending order or descending order (d) no order 101. -percentage of values of a series are less than Q1 (a) 50 (b) 75 (c) 25 (d) 1078. Breakeven point is a point at which : (a) TR=TC (b)TR=AR (c) TC=AC (d) none of these. 79. In the consumption function C = a+by, the constant b denotes: (a) elasticity (b) MPS (c) MPC (d) none of these. 80. Total cost is equal to: (a) TVC+TFC (b) AFC+AVC (c) AVC (d)AFC 81. Statistics deals with : (a) qualitative information (b)quantitative information (c) both (d) none. 82. Statistical results are: (a) absolutely correct (b) not true (c) true on an average (d) universally true. 83. Statistics are: (a) aggregate of facts (b) numerically expressed (c) systematically collected (d) all of these 84. Statistical methods are: (a) collection of data (b) classification (c) analysis and interpretation of data (d) all of these. 85. An attribute is: (a) a qualitative characteristic (b) a quantitative characteristic (c) a measurable characteristic (d) all these. 86. Tally marks determine: (a) class width (b) class boundary (c) class limit (d) class frequency 87. When the upper limit of a class is the lower limit of the next class, the series is known as : (a) Exclusive (b) inclusive (c) individual (d) discrete 88. Pie diagram is used for : (a) comparing different components and their relations to total (b) representing qualitative data in a circle (c) representing quantitative data in a circle (d) either b or c66. In the function Y = f(X), X is the : (a) dependent variable (b) independent variable (c)constant (d) none of these 67. The function g(x)= 2x2 - x + 7 is : (a) linear (b) biquadratic (c) quadratic (d) constant function. 68. The function log y = a+ bx is called: (a) linear function (b) double log function (c)exponential function (d) semi log function . 69.

The graph of a quadratic function is a: (a) line (b) hyperbola (c) parabola (d) none of these 71. In a rectangular hyperbola, the relationship between X and Y is: (a) direct (b) indirect (c) linear (d) no relationship. 72. The parabola X2 = -4py lies completely: (a) above the X axis (b) right side of the Y axis (c) below the X axis (d) left side of Y axis. 73. For equilibrium price and quantity demanded , the condition is : (a) demand > supply (b) demand number of columns. (b) number of rows
