Six Flags Fiesta Texas in San Antonio was interested in the average wait time at their most popular roller coasters at the peak park time (2 p.m.). They selected 15 patrons and had them get in line between 2 and 3 p.m. for Coaster 1 and they selected 18 patrons to get in line at Coaster 2. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes): Coaster 1: 122, 124, 115, 118, 99, 126, 152, 118, 119, 123, 85, 135, 118, 65, 75.Coaster 2: 80, 51, 110, 118, 48, 120, 118, 115, 150, 115, 106, 118, 111, 120, 120, 89, 61, 56Compare the following (a through k) for these two samples and then help the park identify which of the two roller coasters is more popular (explain why): Coaster 1Coaster 2a. Means b. Q1 (or 25th percentile) c. Median d. Q3 (or 75th Percentile e. Standard Deviations f. Ranges g. Interquartile Ranges

Question

Six Flags Fiesta Texas in San Antonio was interested in the average wait time at their most popular roller coasters at the peak park time (2 p.m.). They selected 15 patrons and had them get in line between 2 and 3 p.m. for Coaster 1 and they selected 18 patrons to get in line at Coaster 2. Each was given a stopwatch to record the time they spent in line. The times recorded were as follows (in minutes):

Coaster 1: 122, 124, 115, 118, 99, 126, 152, 118, 119, 123, 85, 135, 118, 65, 75.

Coaster 2: 80, 51, 110, 118, 48, 120, 118, 115, 150, 115, 106, 118, 111, 120, 120, 89, 61, 56

Compare the following (a through k) for these two samples and then help the park identify which of the two roller coasters is more popular (explain why):

	Coaster 1	Coaster 2
a. Means
b. Q1 (or 25^th percentile)
c. Median
d. Q3 (or 75^th Percentile
e. Standard Deviations
f. Ranges
g. Interquartile Ranges

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
