Answer Part 1 Part 2 And Part 3 To The Fullest

I’m working on a statistics multi-part question and need an explanation to help me understand better.

Part 1:

1. Explain the four types of measurement scales.
2. How is the interval scale more sophisticated than the nominal and ordinal scales?
3. Why is the ratio scale the most powerful of the four scales?
4. Briefly describe the difference between “attitude rating” scales and “attitude ranking” scales, please indicate when each is used.
5. Describe if attitude ranking and attitude rating are mutually exclusive.
6. Why is it important to establish the “goodness” of measures and how is this done?

Part 2:

1.Define reliability and validity in the context of qualitative research.

2.Discuss how a researcher can assess the reliability and validity of qualitative research.

3.Describe how narrative analysis differs from content analysis.

4.Explain how deductive reasoning is different from inductive reasoning and when a researcher should apply them.

Part 3:

An investigation of the effectiveness of a training program to improve customer relationships included a pre-training and a post-training customer survey. To compare the differences, they computed (post-training survey score − pre-training survey score). Seven customers were randomly selected and completed both surveys. The results are shown in table below:

1. Calculate the mean and standard deviation of the two samples.
2. Decide on an appropriate method to test the hypothesis that on average the training has been effective.
3. Specify the null and the alternate hypotheses.
4. Calculate the sample value of the (test statistic).
5. Calculate the p value.
6. Assuming a 5% level of significance, decide to reject or not to reject the null hypothesis
7. Interpret your decision.
