You can find numerous methods used to collect or obtain information for statistical analysis. Three of probably the most practices which are popular:

•        Usage data

•        Checklists

•        interviews

•        Direct Observation

•        Experiments

•        Surveys.

These strategies are the axioms that will work the Data Collection Tools

Observation

1.     Studies.

  A survey is employed to investigate the characteristics of a population. It is frequently used when the subjects are people, and concerns are expected of them. When making a survey, you must be very careful of wording (and sometimes purchasing) the relevant questions so that the outcomes aren't biased.

 A survey gives information from the social people; E.g.  Pre-election polls; marketing surveys.

Surveys may be administered in lots of ways, e.g.

•        Personal interview

•        Telephone Interview, and 

•        Self-Administered Questionnaire.

1.     Direct observation

Direct observation it is common for the observer to be present who sits passively and documents as accurately as possible what is being conducted. Usually, it is the behavior of one or more people that is recorded, and an advantage of the strategy is several people communicate with one another, and also the piece that is the same or could be observed. A variation with this technique is to have a camera that is a video during the point of usage, which records interactions that can later be watched and analyzed by an observer

Direct observation is employed when other information collection procedures, such as surveys, questionnaires.

2.     Experiments

• In an experiment, a researcher assigns a therapy and observes the response. Sometimes, a control group might be used to compare the potency of therapy.

3.     Case studies

An example is a research approach that is used to generate an in-depth knowledge of an issue that is complex in its real-life context. Instance studies are good for describing, comparing, evaluating, and understanding different factors of an extensive research problem

4.     Checklist

It is one of the most commonly utilized instruments for performance evaluation. The observer is enabled by a checklist to note just whether or not a trait is present.  It consists of a listening of steps, activities, and behaviors which the observer records when an incident occurs.  

5.     Interviews

A meeting is a conversation for gathering information.  Interviews are acclimatized to collect data from friends that are little on a wide range of topics.
