Qualitative:
Qualitative data/research is when someone does not require the measurement. It mostly consists of facts and information, the way someone can get this information is by an interview and/or questionnaire. The way you can remember this is by using the word quality, which represents the word qualitative.

Quantitative:

Quantitative data/research on the other hand uses measurements because it consists of numbers, statistics and figures. People can also get this by questionnaires and then putting their results in excel and putting them into graphs, pie charts and/or bar charts. The word that can represent quantitative is quantity that links back to numbers.

Reliable:

This means when a person, data and/or facts is seen as trusted, and able to use in your research. It also means that it is consistently good in quality and/or performance. Also, to find out if something is reliable you can keep testing, whatever, you are doing. For example, scientists will carry out experiments and to find out if it is reliable they would keep testing it out three times and if they get the same or similar results, it is seen as reliable.

Validity:

Validity means when something is acceptable and you are able to use there and then. If it is invalid, this means that you are not able to use it because it either expired or not up to date. For example, if you have a train ticket and the departure time is at 5 o’clock and you get at the station at around 4:30, your ticket will be valid, but if you get there after 5 the ticket will be invalid.    

Primary Research:

This is also known as field research because to get the information you need you will have to go out to the public and get the information by interviewing, and questionnaires. An advantage of using primary data is that the researcher will be able to focus on both qualitative and quantitative issues. However, primary research can be more expensive than secondary research.

Secondary Research:

This is known as desk research because you don't have to go out and get the information. The reason for this is because you are able to gather information that already exists. This includes reports from a library, already made surveys and the internet.
