The three types of qualitative research are phenomenological, grounded theory, and ethnographic research. compare the differences and similarities between two of the three types of qualitative studies and give an example of each.

Answer with Step-by-step explanation:

There are three types of qualitative research are as follows:

1) Phenomenological

2) Grounded theory

3) Ethnographic research

Phenomenological is a method of explaining that exists as an integral part of the world.

For example, we all know very much about the 'counselors' but what does actually 'counselor' means?

Ethnographic research is the study of mankind that gives scientific description of individual human societies.

For example this type of research includes traditional anthropologic texts and it can be done by conducting interviews too.

Grounded theory is the theory that theory which is emerged from the data which is collected.

For example In this method, article is discussed theoretically and then use a visual mode to show how to use grounded theory.

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
