Positive Correlation

Positive correlation: If the increase or decrease in one variable affects the increase or decrease in another variable, we say that the two variables are positively correlated. Negative correlation: If the increase or decrease in one variable affects the decrease or increase in another variable, we say that the two variables are negatively correlated. Correlation coefficient: It studies about the degree of the relationship between the two variables. Or it studies about the strength of the two variables.
The advantages and disadvantages of correlational studies: Advantages: It gives the idea about the linear relationship between two variables, whether they are correlated. Disadvantage: Correlation does not mean that one variable "caused" the other variable to change. If the change in one variable affects the change in the other variable, then we say that two variables are correlated. Types of Correlational Designs: There are many methods for correlational studies with their own strengths and weaknesses. One trendy method is called naturalistic observation, which necessitates a researcher to …show more content…
A lapse of this particular research method is that the researcher has no way of knowing if the original data collection methods were reliable. Correlational studies are a helpful tool for conducting research. However, it must be kept in mind that no study method is perfect. Researchers must take into consideration the limitations of both their preferred research method and correlational studies as a general rule. Correlational designs may be cross-sectional, in which all observations are made at the same point with context of time, or they may be longitudinal, in which calculations are made at two or more different time points Correlation is not
