Exercises for Handout 5: Chapter 2 Quiz: 3) In order for the date values 05May1955 and 04Mar2046 to be read correctly, what value must the YEARCUTOFF= option have?

2

a. value between 1947 and 1954, inclusive – This answer is INCORRECT as four digit year inputs do not rely on the YEARCUTOFF option and are read correctly assuming the informat width is set to read the entire date value.

b. 1955 or higher – This answer is INCORRECT as four digit year inputs do not rely on the YEARCUTOFF option and are read correctly assuming the informat width is set to read the entire date value.

c. 1946 or higher – This answer is INCORRECT as four digit year inputs do not rely on the YEARCUTOFF option and are read correctly assuming the informat width is set to read the entire date value.

d. any value – This is the CORRECT answer because if the informat width is set correctly to read in the entire date value, YEARCUTOFF does not matter. YEARCUTOFF only comes into effect when 2 digit year dates are given (eg. 2002 as “02” and 1992 as “92”).

8) Which time span is used to interpret two-digit year values if the YEARCUTOFF= option is set to 1950?

a. 1950-2049 – This is the CORRECT answer as YEARCUTOFF specifies what year the 100 year range begins at, in this case it starts at 1950 and 100 years later is 2049. (starts 1/1/1950 ends 12/31/2049)

b. 1950-2050 – This is an INCORRECT answer as this is a span of over 100 years (starts 1/1/1950 ends 12/31/2050)

c. 1949-2050 – This is an INCORRECT answer as the start date is before 1950 and the period given is over 100 years (starts 1/1/1949 ends 12/31/2050)

d. 1950-2000 – This is an INCORRECT answer as this is not a 100 year period. Chapter 18 Quiz: 1) SAS date values are the number of days since which date?

a. January 1, 1900 - This is INCORRECT as SAS Date values are the number of days from 1/1/1960 to the given date.

b. January 1, 1950 – This is INCORRECT as SAS Date values are the number of days from 1/1/1960 to the given date.

c. January 1, 1960 – This is CORRECT as SAS Date values are the number of days from 1/1/1960 to the given date.

d. January 1, 1970 – This is INCORRECT as SAS Date values are the number of days from 1/1/1960 to the given date.

2) A great advantage of storing dates and times as SAS numeric date and time values is that

a. they can easily be edited. – This is INCORRECT as all date and time values in all programs are generally easily edited.

b. they can easily be read and understood. – This is INCORRECT as SAS numeric date and time values are not easily read as they are derived from set YEARCUTOFF and beginning date options.

c. they can be used in text strings like other character values. – This is INCORRECT and not true, the values are stored as numeric characters.

d. they can be used in calculations like other numeric values. – This is the CORRECT answer as the advantage of SAS is that it reads in time and date values as numeric variables and allows us to calculate desired values much more easily.

3) SAS does not automatically make adjustments for daylight saving time, but it does make adjustments for:

a. leap seconds – This is INCORRECT as SAS does not adjust for leap seconds. b. leap years – This is CORRECT as SAS automatically makes adjustments for leap years. c. Julian dates – This is INCORRECT as SAS does not adjust for Julian dates. d. time zones – This is INCORRECT as SAS does not adjust for time zones.

4) An input data file has date expressions in the form 10222001. Which SAS informat should you use to read these dates?

a. DATE6. – This is INCORRECT as this is the wrong informat to use for the given date expression.

b. DATE8. – This is INCORRECT as this is the wrong informat to use for the given date expression.

c. MMDDYY6. – This is INCORRECT as the wrong width is specified. d. MMDDYY8. – This is the CORRECT answer as the first two digits will read in the month,

the second two (DD) the date, and the third two (YY) as they year. The number 8 at the end specifies the total width of the inputted value so that the entire expression may be read correctly. Note that YY in this case will read the entire 4 year digit (2001) due to the correct width of 8 being specified.

5) The minimum width of the TIMEw. informat is:

a. 4 – This is INCORRECT as the minimum width of TIMEw. informat in SAS is 5. b. 5 – This is the CORRECT answer as this is the minimum width of TIMEw. informat in

SAS. c. 6 - This is INCORRECT as the minimum width of TIMEw. informat in SAS is 5. d. 7 - This is INCORRECT as the minimum width of TIMEw. informat in SAS is 5.

6) Shown below are date and time expressions and corresponding SAS datetime informats. Which date and time expression cannot be read by the informat that is shown beside it?

a. 30May2000:10:03:17.2 DATETIME20. - This is an INCORRECT answer as SAS reads this correctly.

b. 30May00 10:03:17.2 DATETIME18. - This is an INCORRECT answer as SAS reads this correctly. c. 30May2000/10:03 DATETIME15. – This is an INCORRECT answer as SAS reads this correctly. d. 30May2000/1003 DATETIME14. – This is the CORRECT answer, the hour, minutes and

seconds value must be separated by a delimiter in order for SAS to read it in correctly. 7) What is the default value of the YEARCUTOFF= system option?

a. 1920 – This is the CORRECT answer as the default YEARCUTOFF is 1920. b. 1910 – This is an INCORRECT answer as the default YEARCTUFOFF is 1920. c. 1900 – This is an INCORRECT answer as the default YEARCTUFOFF is 1920. d. 1930 – This is an INCORRECT answer as the default YEARCTUFOFF is 1920.

4

8) Suppose your input data file contains the date expression 13APR2009. The YEARCUTOFF= system option is set to 1910. SAS will read the date as:

a. 13APR1909 – This is an INCORRECT answer as YEARCUTOFF does not affect 4 digit year values such as the one given.

b. 13APR1920 – This is an INCORRECT answer as YEARCUTOFF does not affect 4 digit year values such as the one given.

c. 13APR2009 – This is the CORRECT answer as the YEARCUTOFF range does not come into effect as the date given is a 4 digit year value.

d. 13APR2020 – This is an INCORRECT answer as YEARCUTOFF does not affect 4 digit year values such as the one given.

9) Suppose the YEARCUTOFF= system option is set to 1920. An input file contains the date expression 12/08/1925, which is being read with the MMDDYY8. informat. Which date will appear in your data?

a. 08DEC1920 – This is INCORRECT as the year would be read in as 2019 given the wrong informat code.

b. 08DEC1925 – This is INCORRECT as the year would be read in as 2019 given the wrong informat code.

c. 08DEC2019 – This is the CORRECT answer as the specified informat width is wrong; only the first 8 characters are read (it will be read as 12/08/19) and because the YEARCUTOFF option is set to 1920 (1/1/1920 to 12/31/2019), the date 12/08/2019 will appear in the data.

d. 08DEC2025 – This is INCORRECT as the year would be read in as 2019 given the wrong informat code.

10) Suppose your program creates two variables from an input file. Both variables are stored as SAS date values: FirstDay records the start of a billing cycle, and LastDay records the end of that cycle. The code for calculating the total number of days in the cycle would be:

a. TotDays=lastday-firstday; - This is an INCORRECT answer as you must subtract the last date by the first date and also add one in order to find the correct range.

b. TotDays=lastday-firstday+1; - This is the CORRECT answer as you must subtract the last date by the first date and add one in order to find the correct range.

c. TotDays=lastday/firstday; - This is an INCORRECT answer as you must subtract the last date by the first date and also add one in order to find the correct range.

d. You cannot use date values in calculations. – This is an INCORRECT answer as SAS is able to use date values in calculations due to the way they are stored.

A00-201 Practice Exam:

Q91: Answer is D. An order variable can display Rows in a report to be ordered the order variable. Totals are computed for all numeric variables for different values of group variables if group is used. In this case, using order defines style variable.

A is incorrect because order not display option needs to define the variable of style.

B is incorrect because order option needs to define the variable of style.

C is incorrect because order not group option needs to define the variable of style.

Q92: Answer is C. In this case, display option is used to define the variable of style and list every observation which meet the where statement.

A is incorrect because display option not group needs to use to define the variable of style.

B is incorrect because display option not across needs to use to define the variable of price. Across is used to get frequencies for each value of across variables.

D is incorrect because display option not order needs to use to define the variable of style.

Q96: Answer is B. The option group is used to compute statistics (sum, mean, …) for numeric variables for different values of group variables. In this case, we need to get mean of price for different values of style, so group needs to use to define the variable of style.

A is incorrect because group option not order needs to use to define the variable of style.

C is incorrect because group option not across needs to use to define the variable of style.

D is incorrect because group option not display needs to use to define the variable of style.
