Exercise 2

The file FalseRecognitionExp.sav contains the proportion of words recognized in an experiment by participants who were tested on three categories of words: words that were not presented in lists of strong associates of the missing word (variable preccnp ); words that were presented in lists of strong associates of the presented word ( preccpp ); or words that both were neither presented nor had any lists of strong associates presented ( preccnn ).
1. Prepare a table that shows the means of the three variables in descending order. Include in the table each variable's standard deviation, minimum, and maximum value.
2. Present a single boxplot of the three variables. Use the variable name to label cases. What does the plot reveal about the shape of the distribution of each variable and about the presence of unusual scores
