Qualitative research tools

There are many types of qualitative research tools, but choosing the proper one is where most people fail. This is one among the most commonly used methods where a lot of information is required about that person before making any conclusion or further investigation

Direct Observation

In direct observation, you can easily write down information by observing people. This observation begins with the first interaction with the subject. There is structured and unstructured observation where one requires participation from the subject while other does not.

Structured observation

There are many variables to make sure that the observation is legitimate. This observation takes into account the participation, behaviour and environmental factors. The notes are made and checked to ensure that information is reliable.

Interview method

Another most common type of instrument researchers use is the interview method where the subject is asked a question. There are many other types of interview methods; some of them are:

  • Face to face
  • In-depth interview
  • Clinical interview
  • Discussion group
  • Focus group

Quantitative research tools

This is a survey method where there is a question which requires short answers, and generally, these questions are close-ended. Some generally used survey methods include

The dichotomous question: This type of question only requires yes or no as the answer.

The multiple-choice question: As the name suggests this type of question has many answers, and the subject is asked to tick what he or she feels is right.

Rank order scaling: This scaling involves ranking a certain set of products based on the given attributions.

The rating scale: This survey method requires the subject to rate a product based on a well-defined explanations and other attitudes.

The staple scale: The staple scale asks the subject to directly rate the brand on a scale which has positive as well as negative scoring.

Open-ended questions: Open-ended questions explore the in-depth aspects of a particular issue, and this gives them time for the person to explain the issue as well as his response.

The demographic questions: This is one of the most integral part of a questionnaire where details such as age, gender, race, income and other details are filled in.
