Types of Inductive Reasoning
The following types of inductive reasoning depend on two factors:
- Methods of defining the sample from the larger population.
- The method of collecting premises to draw a conclusion.
01. Generalization:
In this type of inductive research, the researcher draws a conclusion from a generalization. This means that the premise is made from the research sample, and the conclusion is drawn from the population.
For example, if three out of four students can play football, then all the students can probably play football.
02. Statistical generalization:
In this type, the conclusion is made based on the statistically verified sample. This means that the research sample statistically represent the target population.
This is considered more reliable as the sample is selected randomly and is large.
03. Anecdotal generalization:
Here, a researcher draws a conclusion based on the general features of the sample group.
04. Prediction:
This kind of inductive research makes a prediction based on the sample (current or past). In this reasoning, the researcher collects the premise from the phenomenon and draws a general prediction of the probability of happening of the future event.
05. Analogous:
Inductive reasoning based on analogy means that you draw a conclusion about new properties of two populations from the shared attributes of the samples of the two populations.
For example, say samples of populations 1 and 2 have common characteristics of u,v, and w. The property x observed in population 1 can also be said to be the property of population 2.
06. Causal inference:
Here, the conclusion is drawn based on the causal connection between the samples of different populations. The validity of this conclusion is very low as it can only be confirmed by examination.
Now let’s move on to the types of deductive reasoning better to understand the process of inductive vs. deductive research.
Types of Deductive Reasoning
There are three types of deductive reasoning based on two factors:
- The premise
- The kind of relationships across the premise.
01. Syllogism:
It is a commonly used type of reasoning in deductive research. It includes a set of premises followed by a conclusion.
- The first premise – a conditional statement.
- The second premise – a conditional statement that connects with the conclusion of the 1st premise.
- Concluding statement – combines the first part of the 1st premise with the second part of the 2nd premise.
02. Modus ponens:
In this type of deductive reasoning, the second premise generally affirms the first part of the first premise.
For example,
1st premise: If it’s raining today, I will wear my raincoat.
2nd premise: it is raining today.
Conclusion: I will wear my raincoat.
03. Modus tollens:
This kind of deductive reasoning is also known as the law of contrapositive. It is the opposite of modus ponens. In this reasoning, the second premise contradicts the first part of the first premise.
For example,
1st premise: If it’s raining today, I will wear my raincoat.
2nd premise: I will not wear my raincoat.
Conclusion: It is not raining today.
