摘要:If the correlation exists between the above two factors then it could mean either one of them influences the other or both of them influence each other consistently or intermittently or both of them are influenced by some other third factor or the correlation could be out of pure chance.
A comprehensive statistical analysis on the relationship between the two variables investment fund performance and investment fund management fee.The project aims at drawing (statistical) conclusions about the relation(if any) between the performance of the investment funds(in terms of price) and money spend as the cost of managing the respective funds, the significance of the relation and thereby provide some support in decision making for higher level management regarding this. Please note that the project only attempts to find if change in one variable is accompanied by the change in the other and this in no way establishes the cause and effect relationship i.e. we cannot conclude, at least by this exercise, whether increase in spending on the management fees causes increase in the fund performance. (the cause and effect relationship cannot be found by just using statistical techniques but it also requires the exhaustive study of the nature of the funds and the management involved). If the correlation exists between the above two factors then it could mean either one of them influences the other or both of them influence each other consistently or intermittently or both of them are influenced by some other third factor or the correlation could be out of pure chance(i.e. because of the choice of a wrong sample).
We come across similar situations in reality where we need to find whether two or more entities are related to one another and the nature and the degree of their relationships. For example the age of husband and wife, price of a commodity and the amount demanded, an increase in rainfall up to a point and production of rice etc. (examples involving only two entities are considered here because it would be easier to discuss, and the given project also involves only two entities and the same ideas can be extended to the cases involving more than two entities). Since the entities assume different values depending upon the time place or persons these are referred to as variables in Statistics. If a relationship (measurable) exists between the two variables then the variables are said to be correlated. The measure of the correlation called the correlation coefficient or the correlation index gives the degree and the nature of the correlation (i.e. increase in one variable corresponds to increase or decrease in the other variable) in terms of a number. The correlation analysis deals with the techniques used in measuring the closeness of the relationship between the variables.
We give some important definitions in this regard:
Correlation Analysis deals with the association between two or more variables. (By Simpson and Kafka).
If two or more quantities vary in sympathy so that movement in one tends to be accompanied by a corresponding movement in the other(s) then they are said to be correlated.(by L.R.Connor)
When the relationship is of a quantitative nature, the appropriate statistical tool for discovering and measuring the relationship and expressing it in brief formula is known as correlation. (Croxt on and Cowden).
There are several ways of classifying correlation. Three of the most important are:
positive (direct) or negative (inverse)correlation:- if one variable increases the other variable also increases on average and if one decreases the other decreases on average then they are said to be positively correlated. If one variable increases and the other decreases on avera
