Question

On a professional football team, such as the Seattle Seahawks, players on the field may play a variety of positions but are generally classified as linemen (who begin each play on the line of scrimmage) or part of the backfield (such as a quarterback or a running back). The weight (in pounds) of each Seahawk lineman (as listed at seahawks.com on January 13, 2006) is shown below. player weight Alain Kashama 262 Joe Tafoya 265 Bryce Fisher 272 Grant Wistrom 272 Craig Terrill 287 Rocky Bernard 293 Robbie Tobeck 297 Chuck Darby 298 Sean Locklear 301 Wayne Hunter 303 Rodney Bailey 305 Chris Gray 308 Walter Jones 308 Chris Spencer 309 S. Hutchinson 313 Marcus Tubbs 320 Ray Willis 327 Floyd Womack 330 Compute each of the following summary statistics. Round your answers to the nearest 0.1 pounds. Consider the data to be the full population. median = 302 pounds IQR = pounds mean = pounds standard deviation = pounds

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.
