Water quality for a sample of lakes in Florida
A data frame with 53 observations on the following 12 variables.
IDAn identifying number for each lake
LakeName of the lake
AlkalinityConcentration of calcium carbonate (in mg/L)
CalciumAmount of calcium in water
ChlorophyllAmount of chlorophyll in water
AvgMercuryAverage mercury level for a sample of fish (large mouth bass) from each lake
NumSamplesNumber of fish sampled at each lake
MinMercuryMinimum mercury level in a sampled fish
MaxMercuryMaximum mercury level in a sampled fish
ThreeYrStdMercuryAdjusted mercury level to account for the age of the fish
AgeDataMean age of fish in each sample
This dataset describes characteristics of water and fish samples from 53 Florida lakes. Some variables (e.g. Alkalinity, pH, and Calcium) reflect the chemistry of the water samples. Mercury levels were recorded for a sample of large mouth bass selected at each lake.
