A researcher would like to match subjects on weight for an experiment on weight control. The weights of each subject in the sample are shown in the table below. Subject Subject Number Weight Number Weight S 115 Sq 122 S 185 $10 160 Sy 163 $11 159 S 122 $12 154 Ss 165 $13 143 So 183 S14 143 184 $15 138 115 $16 137 Match them into pairs and form one experimental and one control group by using random assignment. Carry out the procedure using precision matching, range matching, and rank-ordered matching.
