The field of psychology is nothing without research work because it provides recent knowledge of the field. There are various methods used in psychological research. Correlation is a vital one in the field of psychological research due to its wide use, efficacy and appropriateness. It is important to discuss the concept and explore the relationship for understanding. In this way relationship between two variables is important. Psychology is the field in the world that is conducting more investigations. All these aims of the psychological research meet with the correlations studies. It provides relationships between two or more variables in different aspects. 

The correlational studies provide both positive and negative aspects to describe the concepts, relationships and importance for better understanding.

Without the evaluation of variables impact, relationship and cause, it is not possible to meet the study aim. Thus the use of correlational in psychological research is critical. It makes the studies valid, reliable and easy to understand the cause and effect through measuring the relationship of variables. The use of correlation studies has a significant ratio in psychology. More than 50% of the psychological studies have correlation methods. So, nobody can deny the importance, usage and effectiveness of correlations studies in psychology.

Types of Correlational Studies and Methods of Data Collection

Correlations studies are the root of psychological research to meet the aim of your study. In this way, there are different types of correlational studies that are important to conduct the investigation. Two major types based on the aspects and methods are important. The first one relies on the nature of the relationship, either positive or negative. The second relies on methods of data collection. Expert dissertation helpers have given the following detail of both types.

Relationship Types 

The first type in the correlational studies under psychological studies is positive. It describes that there is a positive relationship between the variables. For example, both variables will be in the same direction. If the learning capacity increases, then performance will also increase. These are important in both applied and clinical studies because, without them, the relationship between statistical values and numbers is not possible. The second type is the negative correlation in psychological studies. It means that if one variable effect increases, the other will reduce. Like both variables shows a negative relationship. For example, psychological well-being resulted in less stress. The last one is the zero correlation which means there is no causal effect. In this type of study, findings explore that there is no relationship between variables. For example, gender has no effect on creativity.

Data Collection Methods Types

The second category of correlational studies relies on the way of data collection. The first thing in this type is the natural observation correlation studies. In these kinds of psychological studies, the data collected by the researchers from nature and observation. The observation of human behaviour without experiment is the best example. The second type of this study uses previous data for the new study. This type of the studies considered an archive type of correlation investigation. An example of this study is review studies on the different aspects. The last important type is the survey type study. In these kinds of correlation psychological investigations, the data used from the target population according to the variables and aim of the study. This type of study has a significant role in psychological studies. Survey through online channels and close-ended questioners are the recent trends in this type of study.

Importance 

Correlation studies are important in psychological investigations as they play a vital role. Without examining the relationship and casual effect, the investigations are not valid and reliable to explore the main aim and objectives. The first important aspect of correlational studies is to provide the appropriate population. The inappropriate target and sample led to poor findings and led to vague results. The correlation methods must be clear about the sample size and features of the population. The second important role in psychological research is to measure the impact of one variable on the other, which is possible with correlation only. It helps measure and test the relationship between two or more variables in the selected research topic. It is important in psychological research to present the findings in numbers and values because descriptive data leads to complications for understanding the concepts. Correlation study in the psychological field is a core method that provides statistics of the relationship.

Uses and Advantages 

Explore Relationship 

Correlation studies in psychology are important to explore the relationship. It reduces the ambiguities and provides the available facts and figures. Through this nature, it is possible to measure positive and negative relationships.

Provides Easy Way of Data Analysis 

Before finalising the methods, a good researcher always minimises the issues of data collection. The correlational studies are effective and have a framework for data analysis. In this way, it saves the efforts and cost of psychological research.

Less Time Taking 

Correlational studies are easy as compared to experiments and cross-sectional. This kind of investigation saves money as compared to experimental methods. It also takes less time and manages the information in a proper way.

Valuable Predictions 

Through correlational studies, it is possible to predict human behaviour and present the results in numbers in place of the descriptive data. In the other methods, it is not easy to predict the final results due to having complex data. 

Conclusion 

Correlational studies in psychological research are crucial to predicting human behaviours. It is easy to research in the field of psychology with this method and present findings in the given time. Based on the findings and usage of correlation in psychology, it is clear that it has a significant role in making the studies effective and applicable in the field. Without correlation studies, it is impossible to conduct valid and meaningful research. It is an easy and effective approach to exploring the relationship between variables. It is a less time taking and cost-saving method in psychological research
