Measures of Central Tendency Measures of central tendency are measures which are representative of a sample or population. Central tendency provide the means for one to be more objective when collecting data or making inferences. These measures distinguish the center or middle of a set of values and best characterize the distribution. The central tendency

SD of y = 2247 Solution 4: The coefficient of variation is as follows: The coefficient of variation for x is: 0.000447. The coefficient of variation for y is: 0.000445.

When dealing with machine generated data‚ we often tend to see the data to have better understanding of a structural form. Many such data can be represented in the form of graphs. By laying out a graph‚ we can untangle information and intuitively show relations of objects. Automated graph drawing remains a difficult placement and layout problem. This problem

Examine the reasons why some sociologists choose to use official statistics when conducting research. Firstly‚ official statistics are a source of secondary quantitative data which are gathered by the government or other official bodies. Many reasons for their use by sociologists when conducting research stems from the fact that they are a form of secondary data; meaning that they are not collected by the sociologist themselves. This makes them high in practicality‚ representativeness and reliability
