Solution 1.

Two continuous variables are: - Q2: How long have you practiced as a social worker?

- Q16: What is your age in years?

Social worker’s experience ranged from 1 to 27 years (M=7.5 years, s.d.=6.86) and the age of respondents in the sample ranged from 14 to 74 years (M=36.31, s.d.=13.57) 2.

Two nominal variables are: - Q1: Are you a social worker?

- Q9: I have considered a career in the social work profession.

Results indicated that 88% (n=304) of the respondents were social workers and 91% (n=314) of the respondents in the sample have considered a career in the social work profession.

3.

Two ordinal variables are: - Q4b: How useful were the resources provided by the social worker?

- Q5: How would you rate your overall experiences with a social worker? statisticsassignmenthelp.com statisticsassignmenthelp.com

Results indicated that 46% (n=63) of the respondents were very useful were the resources provided by the social worker, 34% (n=46) were useful, 7% (n=10) were somewhat useful and 13% (n=18) were not useful.

Results indicated that 3% (n=4) of the respondents rated “very bad” as the overall experiences with a social worker, 4% (n=5) rated “bad”, 17% (n=22) rated “average”, 45% (n=58) rated “good” and 32% (n=41) rated “very good” as the overall experiences with a social worker.

4.

For Q3: “How frequently do you interact with social workers?” which had four options ranging from 0 to 4 in the question were also entered 5 as the answer by case IDs: 268, 280, 309, and 320.

For Q4: “Have you ever received services from a social worker?” which had two options: 0 (Yes) and 1(No) in the question were also entered 2 as the answer by three case IDs namely: 221, 268 and 280.

One of the respondents for Q4a, answered 2 and another one answered 10 which is not correct answer to the question.

One of the respondents for Q7, answered 100 which is not correct answer to the question. statisticsassignmenthelp.com statisticsassignmenthelp.com

5.

There are many questions in the survey which answer this question in one way or the other and the descriptive statistics for all these questions are provided in the table below. It can be seen that the values of all the three measures of central tendency are close to 3 which means “good” for the overall experiences with a social worker. However, the survey does not include a respondent which has rated “very bad” and “very good”. Values of all the three measures of central tendency are more than 8 for “overall view of social work profession” suggesting “positive” view. With regard to importance of the profession, measures of central tendency are greater than 8.5 suggesting quite important. All the three measures of central tendency for the questions regarding the importance of Hospice, hospital, school, mental health centers are greater than 4 suggesting social workers are important and for prison and non-profit management, mean is greater than 3.5 indicating between close to important.

Thus, all the questions indicate that the social workers are quite beneficial.

Histograms for the both the variables show that none of these is close to normal.

The mean value of the Q2 and Q16, two continuous variables, is larger than the median value which suggests that the data is positively skewed. It can also be confirmed from the positive skewness values for the two variables i.e. 1.5 and 0.7 respectively. It can also be seen from the larger side tail in the histograms for both the variables. statisticsassignmenthelp.com statisticsassignmenthelp.com
