He has placed the task of identifying the various types of data for a random selection of a few of his variables to his new research assistant. Help Dr. Song's new assistant by identifying the level of measurement of each of the variables listed in the table below. Indicate the level of measurement of each of the variables, and explain why a variable can be categorized as either nominal, ordinal, interval, or ratio. Income | #Homicides | Sex | Age Temperature ("DI suspect $20,215 $150,987 22 $78,002 49 S67,897 S45.6 12 12 S35.815 3 Wendy 21 31 37 29 54 42 35 56 89 102 98 45 36 17 Daniel Albus Sydney Lily Joanne 82 Cynthia S52,270 8 23 67 Ronald $80,903 12 4. According to the UCR, 57% of murders in 2014 were committed with firearms. Suppose that you have a randorm sample of 6 murder cases. Compute two probabilitics: 1) the probability that two or fewer murders were committed with firearms, and 2) the probability that four or more murders were committed with firearms. Show all of your calculations.Explanation / Answer
Income - Ratio (It has a true zero value)
Number of homicides - Ratio (It has a true zero value)
Sex - Nominal (It has only two values, which are categorical)
Age - Ratio (It has a true zero value)
Temperature (F) - Inteval (There is true zero value. Temperature of 0 F doesnt mean that there is no temperature)
Suspect - Nominal (These are also names or categories. So, it is nominal)
