Exercises 1 through 4 (p145)

1. Conduct frequency analysis on the gender and martial status variables. From the output, identify the following:    
(a)   Percent of men 
(b)   Mode for martial status 
(c)   Frequency of divorced people in the sample

Figure 1: Summary statistics for gender

Gender
		Frequency	Percent	Valid Percent	Cumulative Percent
Valid	Men	13	52.0	52.0	52.0
	Women	12	48.0	48.0	100.0
	Total	25	100.0	100.0

(a)   From figure 1, 52% of the participants are men.

Figure 2: Summary statistics for martial status

Marital Status
		Frequency	Percent	Valid Percent	Cumulative Percent
Valid	Married	9	36.0	36.0	36.0
	Divorced	11	44.0	44.0	80.0
	Never Married	5	20.0	20.0	100.0
	Total	25	100.0	100.0

From figure 2, 
(b)   The mode for martial status is “Divorced”. 
(c)   The frequency of the divorced people in the sample is 11.

2.     Create a frequency table to summarise the data on the educational level variable

Figure 3: Frequency table that summarises the data on educational level of the participants

Education Level
		Frequency	Percent	Valid Percent	Cumulative Percent
Valid	Did not graduate from high school	6	24.0	24.0	24.0
	High School Graduate	4	16.0	16.0	40.0
	Bachelor's Degree	8	32.0	32.0	72.0
	Post Graduate Degree	7	28.0	28.0	100.0
	Total	25	100.0	100.0

3.     Create a bar chart to summarise the data from the community population variable.

4.     Write a Participants section describing the participants in Ann’s example.

The sample consists of 25 participants, approximately half of them were women (n=12) while the rest were men (n=13). Figure 2 shows the frequencies and percentages of the martial status of participants. 44% of the participants were divorced, while 36% were married, with the remaining 20% never married. Figure 3 reports the frequencies and percentages associated with the participants’ educational level. Participants with Bachelor’s Degree made up the highest proportion (32%) while High School Graduate the least (16%). Figure 5 shows that community of size from 1,001 to 5,000 was most well represented in the survey with 6 participants whereas community of size more than 100,000 was least represented with only 1 participant.
