Types of Descriptive Research

Predictive studies are used to guess about the possibility of a symptom based on other symptoms that have appeared and then known beforehand.
2. Comparative Study
Research using the comparative method or comparative study is done by comparing similarities and differences as a phenomenon to find out what factors and how certain events arise. Comparative studies are carried out by collecting facts about what factors cause certain symptoms, and then comparing them.
After knowing the differences and similarities of the causes, then it is determined that a factor is the cause of the emergence of symptoms in the object under study, that is the reason for these symptoms to exist. It can also be done by comparing which variables or factors have the most influence on the changes that occur in the research being conducted.
3. Correlation Studies
The purpose of correlation research is to reveal a correlative relationship between variables without knowing whether the relationship is a causal relationship. The purpose of the correlative relationship itself is a relationship that states a change in one variable is followed by a change in other variables. In the correlative relationship, the closeness between the two variables is monitored, therefore this study involves at least two variables.

In the study of a relationship shows a causal relationship. but shows a parallel relationship. The significant correlation coefficient between height and weight illustrates the existence of an association between height and weight, the taller the body weight will also increase, the shorter the weight will be lighter, it does not mean that height affects weight or anything. weight will affect height. Relationship studies can not only be done with two variables, but can also be done more than two variables.
