Which of the following is true of qualitative research methods? Question 5 options: Qualitative researchers must be able to tran

slate numerical data into meaningful narrative information. Qualitative researchers seek to fit their answers into predetermined categories rather than to understand research participants. Qualitative research is less superior for studying topics that involve complex psychological motivations. Qualitative researchers emphasize their samples are made up of representative rather than relevant consumers.

Complete Question:

Which of the following is true of qualitative research methods?

A. Qualitative data may be analyzed qualitatively or quantitatively.

B. Qualitative researchers must be able to translate numerical data into meaningful narrative information.

C. Qualitative researchers seek to fit their answers into predetermined categories rather than to understand research participants.

D. Qualitative research is less superior for studying topics that involve complex psychological motivations.

E. Qualitative researchers emphasize their samples are made up of representative rather than relevant consumers.

Answer:

A. Qualitative data may be analyzed qualitatively or quantitatively.

Step-by-step explanation:

Qualitative data research is a way or method to gather or collect non-numerical information either by observation or by asking crucial questions. It is a scientific method.

Qualitative data research involves the gathering accurate data and one of the way to do this is by carrying out surveys.

Qualitative data research determines WHY a particular action is carried out.

There are various methods of Qualitative data research. They are:

a. Direct Observation

b. In-depth interviews

c. Focus groups

d. Open end surveys

e. Oral History

f. Ethnographic observation

Qualitative data may be analysed qualitatively or quantitatively.

pychu [463]

Answer:

a) P(X=0)=(4C0)(0.75)^0 (1-0.75)^{4-0}=0.0039  

P(X=1)=(4C1)(0.75)^1 (1-0.75)^{4-1}=0.0469  

P(X=2)=(4C2)(0.75)^2 (1-0.75)^{4-2}=0.211  

P(X=3)=(4C3)(0.75)^2 (1-0.75)^{4-3}=0.422  

P(X=4)=(4C4)(0.75)^2 (1-0.75)^{4-4}=0.316

b) E(X) = np = 4*0.75=3

c) Sd(X) =\sqrt{np(1-p)}=\sqrt{4*0.75*(1-0.75)}=0.866

d) P(X \geq 3) \geq 0.98

And the dsitribution that satisfy this is X\sim Binom(n=9,p=0.75

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

X \sim Binom(n=4, p=1-0.25=0.75)

The probability mass function for the Binomial distribution is given as:

P(X)=(nCx)(p)^x (1-p)^{n-x}

Where (nCx) means combinatory and it's given by this formula:

nCx=\frac{n!}{(n-x)! x!}

Part a

P(X=0)=(4C0)(0.75)^0 (1-0.75)^{4-0}=0.0039  

P(X=1)=(4C1)(0.75)^1 (1-0.75)^{4-1}=0.0469  

P(X=2)=(4C2)(0.75)^2 (1-0.75)^{4-2}=0.211  

P(X=3)=(4C3)(0.75)^2 (1-0.75)^{4-3}=0.422  

P(X=4)=(4C4)(0.75)^2 (1-0.75)^{4-4}=0.316

Part b

The expected value is givn by:

E(X) = np = 4*0.75=3

Part c

For the standard deviation we have this:

Sd(X) =\sqrt{np(1-p)}=\sqrt{4*0.75*(1-0.75)}=0.866

Part d

For this case the sample size needs to be higher or equal to 9. Since we need a value such that:

P(X \geq 3) \geq 0.98

And the dsitribution that satisfy this is X\sim Binom(n=9,p=0.75

We can verify this using the following code:

"=1-BINOM.DIST(3,9,0.75,TRUE)" and we got 0.99 and the condition is satisfied.
