1. Complete the small data entry practice exercise we began in class, using your own data and thatprovided on the handout. Once completed, run the correct procedure to obtainfrequency
distribution information for the variables siblings,relationship,exercise, and transportation. In
addition, generate descriptive statistics for the variables age and hours of study. Attach and/or
insert the requested output to the assignment (this includes 4 frequency tables and 1 Descriptive
Statistics table). (5 points)
2. Refer to the class survey. Describe the level of measurement (nominal, ordinal, interval/ratio) and
whether the variable is categorical or quantitative for the following. (3 points)
VARIABLE Level of Measurement Categorical/Quantitative
Age (Q2 on survey) Interval/Ratio Quantitative
Frequency of Texting (Q5c) Ordinal Categorical
Method of Transportation (Q6) Nominal Categorical
Specialty drinks consumed (Q12) Interval/Ratio Quantitative
Consider self spiritual person (Q14) Ordinal Categorical
Further Studies (Q18) Nominal Categorical
3. Identify the level of measurement of each of the following variables (1 point):
a. A survey measures education by asking, How many years of schooling have you completed?

The remaining two questions require hand-calculations (not SPSS):
13. Below are some data from a 2006 survey on family size in British Columbia: (4 points)
Size of Family Frequency Percentage Cumulative
Percentage
2 persons and below 435 42% 42%
3-4 persons 398 39% 81%
5-6 persons 183 18% 99%
7 persons and above 13 1% 100%Total 1029
Using the data above,
a) Calculate and report percentages for the percentage column;b) Calculate and report cumulative percentages for the cumulative percentage column;c) Report the mode; Mode = 2 Persons and Belowd) Explain what the cumulative percentage for the 3-4 persons category means;

The cumulative % for 3-4 Persons means that 81% of the responses were either at or below 3-4
person families.
e) What percent of families have 5 or more people?19% of families have 5 or more persons5-6 persons (18%) + 7 Persons and Above (1%)
14. A researcher asks six (6) Sociology graduate students how many relationships they have been in.
Calculate the mean and the standard deviation from the numbers below. Write out the formulas andshow all of your work. (3 points)
Number of relationships (x) = 3, 5, 2, 6, 4, 1
Mean: 3.5
3+5+2+6+4+1=21
21/6=3.5
Standard Deviation: 1.65
3-3.5= -0.5
5-3.5= 1.5
2-3.5= -1.5
6-3.5=2.5
4-3.5=0.5
1-3.5=-2.5
(-.5)2=.25
1.52=2.25
(-1.5)2=2.252.5
2=6.25
0.52=0.25
(-2.5)2=6.25
.25+2.25+2.25+6.25+0.25+6.25=17.5
17.5-1=16.5
16.5/6=2.75
Variance=2.75
Square root of 2.75=Standard Deviation
