Elementary Statistics (12th Edition)

The mean can be counted by summing all the data and dividing it by the number of data: $\frac{58+22+27+29+21+10+10+8+7+9+11+9+4+4}{14}=16.357$, the mean is 16.357 million. The mode is the data occuring the most times, which here are 4,9 and 10 million. The median is the average of the 1 or 2 (here 2) middle data: (10+10)/2=01, the median is 10 million. The midrange is the average of the highest and the lowest data: (4+58)/2=31, the midrange is 31 million. We cannot see any pattern, however the reason for the highest values being on those days could be because the second day was on a day when people don't go to cinema as much.
