money. • As it is a mean value‚ it does not reflect income distribution. If the distribution of income within a country is skewed‚ a small wealthy class can increase per capita income far above that of the majority of the population. In this respect Median income is a more useful measure of prosperity than per capita income‚ because it is less influenced by the outliers. • Economic activity that does not result in monetary income‚ such as services provided within the family‚ or for barter‚ is usually

set. Frequencies provide statistics and graphical displays that are useful for describing all different types of variables. The Frequencies procedure can produce such statistics as: frequencies (counts)‚ percentages‚ cumulative percentages‚ mean‚ median‚ mode‚ sum‚ standard deviation‚ variance‚ range‚ minimum and maximum values‚ standard error of the mean‚ skewness and kurtosis (both with standard errors)‚ quartiles and percentiles. It can also produce bar charts‚ pie charts‚ and histograms.Basic

see that Dick’s salary is an outlier compared to the mean. b) The median of these seven salaries is $23‚500. I got the median by first putting the numbers in order. Since it is an odd amount of numbers‚ I just find the center of the data after they were in order. This value does not really compare to all of the individual salaries; it has no relation other then it is just in the center. Dick’s salary does not compare to the median because it is the outlier‚ but mostly everyone else’s does because

Q1. (a) ‘Statistics is the backbone of decision-making’. Comment. Ans.(a) Due to advanced communication network‚ rapid changes in consumer behavior‚ varied expectations of variety of consumers and new market openings‚ modern managers have a difficult task of making quick and appropriate decisions. Therefore‚ there is a need for them to depend more upon quantitative techniques like mathematical models‚ statistics‚ operations research and econometrics. Decision making is a key part of our day-to-day
