Question and answer
Under what circumstances would the mode be the preferred measure of Central Tendency?
there can often be a "best" measure of central tendency with regards to the data you are analysing, but there is no one "best" measure of central tendency. [ This is because whether you use the median, mean or mode will depend on the type of data you have (see our Types of Variable guide), such as nominal or continuous data; whether your data has outliers and/or is skewed; and what you are
trying to show from your data. ]

What is the difference between an independent variable and a dependent variable? Give an example of a cause and effect relationship.
Weegy: The difference between an independent variable and a dependent variable: The independent variable is also called an experimental variable. It is the variable being manipulated in the experiment in order to show the effect on the dependent variable. [ The dependent variable is also called the response variable. It is the variable being observed in the experiment. A change in the independent variable is what causes the change (if any) in the dependent variable, which is the purpose of the experiment. *Cause and Effect Sometimes the dependent and independent variables are cause and effect. For example, a study looking at the number of cookies sold versus the amount of money earned can conclude the independent variable of the number of cookies causes the dependent variable, the amount of money earned. However, correlation is not proof of causation. In the example study of bicycle ride length versus the riders' heart rate, the length of the ride may appear to cause heart rates to increase, but the riders' age, health or technique might also cause the change in the dependent variable. ] (More)

How is basic business research different from applied business research?
Weegy: Basic research would basically refer to systematic study which is aimed at fuller knowledge or a deeper understanding of the essential aspects of phenomena as well as of observable facts. [ This would be done with no precise applications towards any processes or products in mind. At the same time basic research could possibly comprise activities with maybe broad applications in mind. On the other hand, applied research id systematic study undertaken to obtain knowledge or understanding which is necessary in order to establish the possible means by which a known and exact need may be met. The terms fundamental or pure research have also been applied to basic research. It refers to research motivated by a scientist's or person's curiosity or keen interest in a scientific question.
