Question one, what is the difference between qualitative and quantitative research? question two, what are the differences between dependent and independent variables? and question three, what does a researcher need to consider about responses to questions? question four, what are the advantages and disadvantage of interviews? so let's start with question one.
00:27
Quantitative research deals with numbers and statistics.
00:51
Well, qualitative research focuses on testing.
01:03
Theories, specifically it deals with words and meanings.
01:39
Quantitative research focuses on testing theories and hypotheses, while qualitative research focuses on exploring ideas and formulating a theory or hypothesis.
02:49
Quantitative research is mainly expressed as numbers, graphs, and tables, whereas qualitative research is expressed in words.
02:55
So if we look at this, quantitative research, for example, we said it's expressed as numbers.
03:01
So something like age, square foot of a house, things that we can express as numbers.
03:18
But qualitative research, we said it deals with words and meanings.
03:22
So this could be color of house, level of education, or type of degree.
03:42
I can't give necessarily numbers to, they don't have numbers already.
03:46
Blue isn't necessarily number two, for example.
03:51
The type of degree of bachelor's versus a master's versus a phd doesn't have a number to it.
03:57
So it would be qualitative research.
04:06
Question two, a dependent variable is a variable that depends on the independent variable.
04:43
They are often referred to as predicted variables, whereas independent variables is a variable that is not dependent on another variable.
05:24
So we can think of this as the independent variable is our input, whereas the dependent variable is our output.
05:37
So for example, if we're looking at somebody's height and weight, which one's the independent versus the dependent? well, height would be the independent variable, and weight would be the dependent variable...
