How did federal legislation support the establishment of unions and union rights?

How did federal legislation support the establishment of unions and union rights? If such legislation had not been passed, do you think that labor organizations would have developed? Would they have succeeded in establishing themselves?

Post an explanation of a threat to internal validity and a threat to external validity in quantitative research. explain a strategy to mitigate each of these threats.

Designing Quantitative Research
Researchers consider validity and reliability with each new study they design. This is because validity and reliability are not fixed but rather reflect a particular study’s unique variables, research design, instruments, and participants.
In the context of research design, two types of validity, which speak to the quality of different features of the research process, are considered: internal validity and external validity. Assuming that the findings of a research study are internally valid—i.e., the researcher has used controls to determine that the outcome is indeed due to manipulation of the independent variable or the treatment—external validity refers to the extent to which the findings can be generalized from the sample to the population or to other settings and groups. Reliability refers to the replicability of the findings.
For this Discussion, you will consider threats to internal and external validity in quantitative research and the strategies used to mitigate these threats. You will also consider the ethical implications of designing quantitative research.
With these thoughts in mind:

By Day 4
Post an explanation of a threat to internal validity and a threat to external validity in quantitative research. Next, explain a strategy to mitigate each of these threats. Then, identify a potential ethical issue in quantitative research and explain how it might influence design decisions. Finally, explain what it means for a research topic to be amenable to scientific study using a quantitative approach.

What program characteristics did you consider when researching possible graduate programs?

Determine educational program characteristics to consider when choosing
a. Choose a nurse with a master's or doctoral degree to interview.
The nurse you choose can be an advanced practice registered nurse or can
have a graduate degree in a specialty area in nursing or another field. The
nurse must hold a position in health care.
b. Interview the nurse.
Questions to ask during your interview include:
i. What degrees do you have in nursing and in other fields?
ii. What is your current position?
iii. What are the educational requirements for your position?
iv. What program characteristics did you consider when researching
possible graduate programs?

What graduate degrees did you consider?
vi. What influenced your decision to obtain the graduate degree you
did?
vii. Are you considering further education? If so, what degrees are you
considering and why?
