OilDeapsorbtion: Effect of Ultrasound on Oil Deapsorbtion

Description Format Details Source

Description

Experiment to measure the effect of ultrasound on deapsorbing oil from sand

Format

A data frame with 40 observations on the following 4 variables.

Salt

Type of water (1=salt water or 0=distilled water)

Ultra

Amount of time each sample was exposed to ultrasound (5 or 10 minutes)

Oil

Amount of oil in the sample (5ml or 10 ml)

Diff

Difference in the amount of oil removed between the ultrasound run and an equivalent control run (no ultrasound) (Diff = Treatment - Control)

Details

This data set is the result of a science fair experiment run by a high school student. The basic question was whether exposing sand with oil in it (think oil spill) to ultrasound could help the oil deapsorb from it better than sand that was not exposed to ultrasound. There were two levels of ultrasound tested (5 minutes and 10 minutes) and two levels of oil (5 ml and 10 ml). There was also a question of whether exposure to salt water or fresh water made a difference so half the samples had salt water, the others distilled water. Each combination of factor levels was replicated 5 times. There were also an equivalent number of control observations run, all factors being the same but without any exposure to ultrasound. Each experimental run was paired with an appropriate control run and the response variable is the difference in the amount of oil removed in the experimental run and the control run.
