Data Selected by Properties : Increasing, Concave Up

 FILE DESCRIPTION AIDS The total number of cases of AIDS in the USA in 4 month intervals from 1982. BADMIN This data set was obtained by dropping a badminton shuttlecock and recording its distance as a function of time. BOTSWANA The population of Botswana from 1975 to 1990. BRAKE The distance in feet a car travels when braking in an emergency stop as a function of the velocity of the car at the time the brakes are applied. CRAB The claw weight versus body weight of fiddler-crabs. DENECKE Paul Denecke, The University of Arizona, conducted the following experiment using a VCR equipped with a digital tape-counter. He put a tape in the unit, set the tapecounter to zero, and, as he started the tape playing, noted the time. He then kept recording the time and the number on the tapecounter. This data set was obtained in this way. It shows the number of revolutions - the number on the tapecounter - as a function of time in seconds. DOVES The population of the collared dove as it spread throughout Britain from 1955 to 1964. DUCKWEED The results of an experiment in which Duckweed fronds - large compound leaves - were counted every week. FREEFALL This shows data that correspond to a sky diver in free fall in a stable spread-eagle position when falling from rest. It shows the sky diver's distance fallen as a function of the time. HOUSTON The population of Houston from 1850 to 1980. JUDGE1 A subject was given some objects and asked to judge their weights where a 98 gram object was assigned the value 100. This shows the result of such an experiment. JUMPS The results of an experiment in which people fell freely from rest from various heights. It shows the distance fallen in feet as a function of time in seconds. KENYA The population of Kenya for the period 1955 to 1990 in 5 year intervals. LEWIS The times achieved every 10 meters by Carl Lewis in the 100 meter final of the World Championship in Rome in 1987. LIZARD Experiments have been performed where a lizard is encouraged to run as fast as possible, starting from rest. The distance run is then measured as a function of time. MOTHS The number of acres defoliated by gypsy moths as a function of time. NSPLAICE The weight of North Sea plaice as a function of time. PEND02 The period of a nonlinear pendulum as a function of the initial angle. PLAICE The results of an experiment relating the weight of plaice to its length. PLANETS This relates the distance of a planet from the sun to the period of the planet, the time it takes for the planet to orbit the sun, a "year". SPHERE The data set was obtained by dropping a Styrofoam ball and recording its distance as a function of time. TOLUENE The vapor pressure as a function of temperature of Toluene. USAPOP The population of the USA from 1790 to 1990 in 10 year intervals. WORLDPOP The world population from 1650 to 1990.
