Telephone Holding Times
An airline has a toll-free phone number that they use for reservations. Sometimes callers have to be placed on hold. The airline conducted a randomized experiment to determine if there was a significant difference in how long a caller would remain on hold depending on what is playing on the call.

Total, 15 callers were sampled for this study. Each column is the number of minutes that the random caller remained on the line until they hung up for each type of recorded message.

NY Times: The Most Economically Diverse Top Colleges
To measure top colleges efforts on economic diversity, The Upshot calculated a College Access Index, based on the percentage of freshmen in recent years who came from low-income families (measured by the share receiving a Pell grant) and on the net price of attendance for low- and middle-income families. The recent Pell (2012 - 2014) number for each college is the average percentage of the freshman class that received a Pell grant in 2011-12, 2012-13 and 2013-14; not all colleges had 2013 data yet. The earlier Pell (2008) value is for the fall of 2007. Average net price is the average total cost of attendance in 2012-13, including tuition, fees, room and board, after taking into account federal, state and institutional financial aid, for students who come from households earning between $30,000 and $48,000 a year and qualifying for federal aid.
Endowment per student is for the year 2011-12 and includes graduate students. The College Access Index is a combination of net price and the Pell average for 2011, 2012 and 2013, using a statistical technique known as a z-score. A college with an average score on the two measures in combination will receive a zero. | statcrunchhelp | Sep 10, 2014 | 4KB | 1350 |

Improving Reading Ability
Results of an experiment to test whether directed reading activities in the classroom help elementary school students improve aspects of their reading ability.

After the eight-week period, students in both classes took a Degree of Reading Power (DRP) test which measures the aspects of reading ability that the treatment is designed to improve. Number of cases: 44 Reference: Moore, David S., and George P. McCabe (1989). Introduction to the Practice of Statistics [Two sample t-test , Summary statistics]
