## 5. SUMMARY STATISTICS ################################# # 5.1 Let's say you were interested in knowing whether older or younger children have a more diverse vocabulary. # You decide to test this by asking 10 older and 10 younger children to describe a picture, and count # the number of different words that they use when doing so. # The following show the results: run the commands to create objects corresponding to older and younger children. older.exp1 = c(28, 29, 30, 32, 33, 35, 36, 37, 38, 39) younger.exp1 = c(22, 23, 25, 26, 28, 28, 29, 29, 30, 75) # Based on these numbers (just by looking, not calculating anything), # does it look like older or younger children have a larger number of words? # ??? # Calculate the mean and median for each age group. # Put your answer below, and show the commands you used to get these answers. mean(older.exp1) # Mean, older children: 33.7 # Mean, younger children: ??? median(older.exp1) # Median, older children: 34 # Median, younger children: ??? # Based on the values you calculated, do you think the mean or median is a # better representation of this dataset? #
