Qualitative is based on surveys, observation, interviews. It deals with open-ended questions, more up for interpretation and discussion. Quantitative is based on data, statistics, concrete facts. It proves or disproves a hypothesis. 
2. A hypothesis is a statement that can be changed but a theory is an established idea and more official. Examples of a hypothesis is "if you get at least 6 hours of sleep, you will do better in tests than if you get less than 6 hours." However, an example of a theory is Sir Isaac Newton's theory of gravity. 
3. Variables are factors that can be adjusted in an experiment. They are used in quantitative research. 
4. Key methods in qualitative: 
- newspapers
- journal articles
- interviews 
- audio and video materials 
Key methods in quantitative:
- numbers 
- statistics 
- solid data 
- concrete facts 
Findings from quantitative research are more rigid and cannot be changed.

Qualitative research is normally related to the interpretivist approach in social science.  

2)A hypothesis is an assumption made before any research has been completed for the sake of testing, however, a theory is a principle set to explain phenomena already supported by data.

 Theory e.g: Einstein's ideas about relativity are an example of the theory of relativity

Hypothesis e.g: If sugar causes cavities, then people who eat a lot of candy may be more prone to cavities.

3) A variable is something that can be changed or altered such as a characteristic. Specific variables are studied in quantitative research whereas qualitative research involves a study of the whole.

4) 
Qualitative research methods : 
-Ethnography/ participant observation : 
the scientific description of peoples and cultures with their customs, habits, and mutual differences

-Focus groups : a research method that brings together a small group of people to answer questions in a moderated setting


Quantitative research methods: 
-survey questionnaires : a research instrument consisting of a series of questions for the purpose of gathering information from respondents through survey or statistical study

-Structured (systematic) observations : a methodology in which an event or series of events is observed in its natural setting and recorded by an independent researcher

-Secondary analysis of data sets :  involves the use of existing data, collected for the purposes of a prior study, in order to pursue a research interest which is distinct from that of the original work

Quantitative:
- focus on numbers and statistics
- systematically measure / approaches
- focus on relationships between two variables

Qualitative:
- deals with words and meanings
-explore concepts and experience further
-aims to study meanings and understanding people's behavior

2) Hypothesis is a statement or predictions to be tested / an assumption [e.g. maybe people who are sad like to wear black]

Theory: principles drawn up from data assessment. [emotions can have an effect on choice of clothing]

3) Variables are constants that are said to have an effect on one another, and is used in quantitative research.

4) Qualitative: 
  1. Ethnography/Participant Observation: observe behavior of targeted participants
  2. Qualitative Interviewing: to understand participants more to collect relative data
  3. Focus Groups: to choose sites and subjects 
 
Quantitative: 
  1. Measurement: start with a broad question and how to quantify a concept 
  2. Causality: to define relationships between two variables 
  3. Generalisation: with finding, can it be generally applied to all individuals?

The main differences between qualitative and quantitative research strategies are - the purpose of the research, type of data collected, form of data collected, the role of the researcher and the final report. quantitative- proof of something, numerical data, sample (facts) qualitative- surveys, interviews, observations etc. Purpose:  Qualitative -to understand social interactions Quantitative-to test hypothesis and make predictions. For qualitative, researcher knows the participant characteristics. For quantitative, participant characteristics are deliberately hidden. 

2. A hypothesis is a statement of expectation or prediction that will be tested by research. A theory is a well-established principle formulated to explain, predict and understand phenomena, to challenge existing knowledge in a particular topic. Hypothesis predicts the relationship between variables in the research process. Theories introduces and describes the knowledge of a particular topic. Example: Hypothesis-The earth is flat. Theory- "Spherical Earth theory".

3. A variable in research is a measurable trait or characteristic that is subject to change under different conditions. Specific variables are studied in Quantitative research, they are not taken into account in qualitative research.

4. Qualitative: interviews, surveys, observations, field notes and reflections. Quantitative: Numerical data, statistics, objective information, facts, precise measurements. Qualitative uses more what and how as a question to find the answers of it whereas quantitative uses specific data to their research. Qualitative examines the breath and depth of a phenomena, quantitative tests specific hypothesis.

 For qualitative research, the purpose was to understand and interpret social interactions, but for quantitative research, the purpose was to test hypotheses, look at cause and effect, also make predictions. That leads to the differences of the strategies they may take. For quantitative research, the data was based on precise measurements using structured and validated data-collection instruments. And for qualitative research,data was based on such as open- ended responses, interviews, participant observations, field notes,  reflections.
 
-What is a hypothesis? What is the difference between a hypothesis and a theory. Provide an example. 
 Hypothesis is an idea or explanation of sth that is based on a few known facts but that has not yet been proved to be true or correct. So hypothesis could be based somebody’s own guesses and ideas, whereas a theory is a proven principle. For example，in 1589s，Galileo demonstrate that the rate of falling of a body is independent of its mass by dropping objects from the top of the leaning tower of Pisa， then his hypothesis became a theory as he proved the hypothesis correct.
 
-What are variables? Are they used in quantitative or qualitative research?
 Variable is a situation, number or quantity that can vary or be varied. It is used in quantitative research.

-What are the key methods of data collection in the qualitative and quantitative research strategies? explain each of them briefly. 
 Qualitative Research are based on human behavior which will reflect more human’s real thought. So it is actually more personal. Quantitative Research is more objective and it take some scientific methods, like precise measurements and validated data-collection, also some instrument had been used.
