**Page 1 of 2**

Measurements of connections between two variables are correlations. The variables that already arise in the collection or population is not measured by the person experimenting. An affirmative correlation is a straight association while the volume of a single variable surges, the quantity of a different variable also surges. In a negative association, the quantity of a single variable increases, and the stages of another variable decrease. In mutually kinds of connections, there would be no indication or resistant that has variations in one variable and the reasons there are changes in another variable. Simply put, indicating that two variables have a relationship and is a correlation.

The most significant idea to take from these is that correlation is not equivalent to interconnection. Numerous prevalent broadcasting bases make the error of presuming that just because dual variables are interrelated, a fundamental association occurs. Association among variables is found in the study correlations. Here are three likely consequences of a correlational revision: no association, a negative association, and a positive correlation. The range association strength is -1.00 + 1.00 is how the factor is measured. Positive Correlations together the variables raise and fall at the similar times. Undesirable associations designate that the quantity of one variable rises, another one falls (therefore the opposite happens again).

Survey Method

One of the most common methods of research is the survey method. Random sampling is an important way of confirming the purpose of the survey outcomes. In this technique, a random sample of contributors completes a survey, test, or questionnaire that is relevant to the area of curiosity.

Advantages

* Additionally malleable than other methods.

* Investigators can gather large amount of information in a fairly small amount of time. It is quick, inexpensive, and relaxed.

Disadvantages

* Contributors can affect the ending result. Several contributors try to satisfy the investigator, tell a falsehood to perceive themselves look enhanced, or have wrong reminiscences.

* The outcome can be disturbed by a misleading sample or meager survey queries.

Naturalistic Observation

Naturalistic observation includes detecting and indicating the variables of attention in the natural setting deprived of intrusion or operation by the person conducting the experiment.

Advantages

* Provides the person conducting the experiment the chance to see the variable of concern in a standard location.

* Will propose thoughts for additional investigation.

* May
