cysts R Documentation
Settling time of amoebic cysts in water.
Description
Data from an experiment on the settling time of amoebic cysts in water for the purpose of water purification. Observations were made of settling time at three different temperatures. The diameter of the cysts was also recorded. Note that each observation is an average of several observations.
Usage
cysts
Format
A data frame with 21 observations and four variables.
- diameter:
average diameter of cysts in micrometers
- temp:
temperature in degrees Celsius
- time:
settling time in seconds
- n:
number of observations
Note
These data are originally from Chang (1945) but are also featured in Rice (2007).
