Simple Graph
The values of the two variables are plotted on a graph paper. We get two curves one for x variables and another for y variables. These two curves reveal the direction and closeness of the two curves and also reveal whether or not the variables are related. If both the curves move in the same direction i, e, parallel to each other either upward or downward correlation is said to be positive. On the other hand if they move in opposite directions then the correlation is said to be negative .
The above methods is used in the case of time series. This methods also does not reveal the extent to which the variables are related.
In research methodology we not only discuss the research methods but also consider the logic behind the method we use in the context of our research study and explain wh
Maximize Z= 3x1 + 2X2 Subject to the constraints: X1+ X2 = 4 X1 - X2 = 2 X1, X2 = 0
Sources of Hypothesis Hypothesis may be developed from various sources. Some of the important sources are the followings: 1. A Hypothesis Arises from Intuition
RANGE Range is the difference between the highest and the lowest value is series. This is the simplest absolute measure of dispersion. Symbolically : R= L- S
In this method variables beings studied are controlled by the investigator. In other the effect of one variable is observed while other relevant variables are held constant
