Correlational research

By Genevieve Green Posted on May 05, The I Correlational research It's a kind of investigation Not experimental, in which researchers measure two variables and establish a statistical relationship between them correlationwithout the need to include external variables to reach relevant conclusions. There are two essential reasons why researchers are interested in these statistical relationships between variables and are motivated to perform correlational research. The first is because they do not believe that the relationship between these variables is accidental, ie a researcher would apply a survey whose use is known a previously chosen group of people.

Correlational research

Correlational Research There are many types of correlational research. The commonality among all Correlational research of correlational research is that they explore relationships between variables. Where descriptive research only described what was going on, correlational research talks about the link between different things.

It is important to understand that correlational research does NOT tell us that variable A caused Variable B, but rather that they are somehow related. Correlational Study Example For example, if I told you that there was a correlation between domestic violence violence between a family members and bowling you would look at me strangely.

Correlational research

But there is a relationship between the variables variable 1- domestic violence, and variable 2- bowling. As more people bowl in the US, more domestic violence occurs, which is correlational research. Does that mean in this correlational study example that bowling causes domestic violence- like you had bad game and take it out on a loved one.

Or domestic violence causes bowling- like you fight with a sibling and feel the need Correlational research take it out on some pins.

As you have already guessed- one does not cause the other to occur, but they are related- for every time people bowl, I can predict that domestic violence will go up, and every time domestic violence goes down I should be able to find a lane at the local bowling alley.

There is a hidden variable that links both of them together.

A Correlational Study Tries to Find a Relationship Between Variables

In this case it is winter time. In the winter more people bowl and more people stay in their homes which increases the chances of domestic violence. Direction of a Correlation Before we examine the different types of correlational research methods, understand that correlations can go in two directions; positive and negative.

For example, domestic violence and bowling. When bowling goes up, so does domestic violence. When domestic violence decreases, so does bowling. For example, consumption of garlic and dating now I am making this one up. The less garlic you eat, the more you date. The more garlic you eat, the less the date.

One variable going in one direction can be used to predict the other variable going in the opposite direction. Correlational Coefficient Scientists measure the strength of a correlation by using a number called a correlational coefficient.

Now you do not have to know how they get the number, but you should know what it means when you see it.

The the number is below zero like. If two variables have a correlation of zero then they have NO relationship with each other. The strength has nothing to do with whether the number is positive of negative. A correlation of. Types of Correlational Studies There are many different ways to show a correlation between two variables.

The Survey Method Perhaps the most common type of research around is survey research. Every time you receive a letter in the mail asking you to take a minute and answer a few questions, or get a phone call begging for ten minutes of your time to speak about how you feel about??????

All surveys have one thing in common, they ask questions.

Now there are good and bad things about surveys in research. The good- no matter how you do it, internet, mail, phone, in person- they are fairly cheap.

You can cover large populations of people easily if you use the phone or internet. The bad aspects of surveys is that 1. Second, people can lie on the survey so you can always question the validity of your data. · Correlational research can find correlation between two variables.

Two variables could be positively correlated, negatively correlated or not correlated at all. Correlation can range from +1 to Correlation doesn’t mean causation.
