Data Selected by Properties : Increasing, Concave Down

 FILE DESCRIPTION CYNTHIA Cynthia's approximate height from age 1 to age 12. JUDGE2 A subject was shown a 400 sq cm square and advised that its area was assigned the number 20 units as area. The subject was then given various numbers and asked to draw a squares with those numbers as the area when compared to the 20 units area. This shows the result of such an experiment. MENTEN The results of an experiment from biochemical enzyme kinetics involving glucose-6-phosphatase. PORSCHE The velocity of an accelerating Porsche 944 Turbo as a function of time. PROBE A student held a temperature probe firmly between her thumb and forefinger while the temperature of the probe was recorded. This shows the temperature as a function of the time. PUPILS1 This shows the result of an experiment in which 10 subjects were briefly exposed to a bright light, causing their pupils to dilate, and then the diameter of each pupil was measured every 0.5 seconds as the pupil expanded. RUBBER The results of an experiment where various known forces are applied to an unstretched rubber band and its stretched length is measured. SMS A spring-mass-spring system with various masses was allowed to oscillate with no friction or gravity. This shows the period in of the oscillations as a function of the mass. STURGEON A biologist measured the length of a sturgeon over a 21 year period. This shows the length in centimeters as a function of the time in years. TAPE Conduct the following experiment using either a VCR or a tape deck equipped with a digital tape-counter. Put a tape in the unit, set the tapecounter to zero, and, as you start the tape playing, note the time. Then record the time every 5 to 10 minutes along with 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. WARM The rise in temperature of the earth from the 1860 figure as a function of time since 1900. WET The movement of the wetting front as a function of time.
