Question
Kunal was asked by his Statistics teacher, Mrs Sharma to compute inter-quartile range and quartile deviation of a set of data which contained positive values. As per Kunal's calculations, IQR was 25 and quartile deviation was 30. Even without checking the calculations, Mrs Sharma declared that the answers are wrong. Is Mrs Sharma correct in her assertion?

Answer

Yes, Mrs Sharma is correct in her assertion, as the value of OD for a set of positive values, cannot exceed the value of Inter-Quartile Range since QD is half of IQR.

Read the following case study carefully and answer the questions 1-2 on the basis of the same:
The production function is a mathematical expression which relates the quantity of factor inputs to the quantity of outputs that result. The short run production function is defined in economics as a period of time where at least one factor of production is assumed to be fixed. The analysis of short run production sets the stage to better understand the supply-side of the market. How producers respond to price depends, in part, on their ability to combine inputs to produce output. This ability is guided by the law of diminishing marginal returns, which states that the productivity of a variable input declines as more is added to a fixed input. If productivity declines, then more of the variable input is needed as the quantity produced increases. This results in an increase in production cost, which means producers need to receive a higher price.
