mean: add hem up and divide by 50
median: sort low-to-high, take the average of the two middle values
mode: the one which occurs most often (if any). I see that 49 occurs at least twice. If two or more values occur the same maximum number of times, there is more than one mode.
3.13 The following data give the 2010 gross domestic product (in billions of dollars) for all 50 states. The
data are entered in alphabetical order by state (Source: Bureau of Economic Analysis).
173 49 254 103 1901 258 237 62 748 403
67 55 652 276 143 127 163 219 52 295
379 384 270 97 244 36 90 126 60 487
80 1160 425 35 478 148 174 570 49 164
40 255 1207 115 26 424 340 65 248 39
a. Calculate the mean and median for these data. Are these values of the mean and the median sample
statistics or population parameters? Explain.
b. Do these data have a mode? Explain.
