DON'T HAND IN THIS SHEET!!!

The variables include…

partnum -- number of each participant

favpet -- type of favorite pet (1=dog, 2=cat, 3=fish, 4=snakes, 5=lizard, 6=turtle, -9=didn't answer)

mamls -- number of pets that are mammals (-9 -- they didn't answer, -8 -- I didn't believe their answer )

reps -- number of pets that are reptiles (-9 -- they didn't answer, -8 -- I didn't believe their answer )

fish -- number of pets that are fish (-9 -- they didn't answer, -8 -- I didn't believe their answer )

pethap -- rating of happiness with their pets (1-15 scale) (missing = -9)

petsmart -- score on a 30 item "pet care" quiz (-9 -- they didn’t take quiz, -8 -- didn't finish quiz )

data (each row is from a single participant -- columns correspond to the variable listing above) …

101 3 2 0 15 12 21

109 4 -9 -9 3 -9 -8

112 1 6 -8 -8 5 22

121 -9 3 4 25 13 -9

122 2 4 3 2 12 28

124 5 4 5 1 15 27

132 6 0 0 12 -9 15

136 3 3 0 0 12 14

1. Enter the data with properly specified variables (i.e., include all the labels and values)

2. Make "totpet" which is the total number of pets (calculated only for those with complete data)

3. Make "petgrp" 1 = 10 or fewer pets, 2 = 11 to 20 pets, and 3 = more than 20 pets

4. Make "petper" as % of pets each person owns of the most pets anyone owns (think!)

5. Make "favtype" as 1= mammals, 2 = fish, 3 = herptiles (lizards, snakes & turtles)

6. Make "hapgrp" that splits folks into those with pet happiness ratings 10 and over (= 2) vs. 9 and under (= 1)

7. Make "petqper" as percent score on pet quiz

8. Make "replove" with 0 = owns no reptiles and 1 = owns at least one reptile

HAND IN THIS SHEET!!

Get the graph (histogram or bar graph as appropriate), freq, mean, std and sem for each variable (original and constructed). For each variable tell whether the mean is a “meaningful” for that type of variable.

| | n |mean | std |SEM | meaningful mean? |

|partnum | | | | | |

|mamls | | | | | |

|favpet | | | | | |

|reps | | | | | |

|fish | | | | | |

|pethap | | | | | |

|petsmart | | | | | |

|totpet | | | | | |

|petgrp | | | | | |

|petper | | | | | |

|favtype | | | | | |

|hapgrp | | | | | |

|petqper | | | | | |

|replove | | | | | |

Compose a "Table 1" (following the example given in Table 1 of the univariate stats handout) for the following variables: totpet, favtype, hapgrp, petqper. Please note: Just compose this table using Word or some other word processing package – there is no SPSS program to construct this type of table.
