1. Input the following information about each of the researchers’ variables into the Variable View screen in SPSS. a. variable name: station type: string b. variable name: format decimals: 0 label: type of programming values: 1=top 40 2=easy listening 3=classic rock/oldies 4=jazz 5=classical 6=talk 99=other

100=no data c. variable name: ads decimals: 0 label: minutes of aired advertisements d. variable name: program decimals: 0 label: minutes of aired programming 2. Input the data values for the variables identified and described in #9, into the Data View screen of SPSS. 3. Use the SPSS Sort function to place data in order from least to most time devoted to advertisements. 4. a. The researcher wishes to analyze stations that have a clearly identified format. Use the SPSS Filter function to omit stations that fall into the “other” or “nodata” categories from future analysis. b. Check to be sure that the Data View screen reflects the placement of the filter. c. Remove the filter. 5. a. The researcher wishes to focus on only stations with a talk format. Use the SPSS Filter function to omit all other stations from future analysis. b. Check to be sure that the Data View screen reflects the placement of the filter. c. Remove the filter. 6. a. The researcher wishes to obtain separate statistics for the stations in each of the format categories. Use the SPSS Split File function to prepare data for such an analysis. (Remember that the appearance of the data screen does not change.) b. Remove the split file designation. 7. The researcher knows that radio all of the stations included in his or her analysis charge $40 in advertising fees for each minute of advertisements broadcast. Use the SPSS Compute function to determine how much money each station collects from advertising fees. 8. Use the SPSS Compute function to determine the amount of time per hour that each station devotes to broadcasts other than programming and advertisements (e.g. news, traffic, weather, etc.).
