Data preparation
ValueMeasured value for the chemical or property in this record We see that values are represented on different scales according to the 'Unit' so it Range from 0 to 37959.28 with a mean of 24.02. it is not easy to do normalization or transformation, but it would be a problem when doing analysis. LocationName of the location sample was taken from. 10 different locations - Achara, Boonsri, Busarakhan, Chai, Decha, Kannika, Kohsoom, Sakda, Somchair, Tansanee. From the picture below, we can see the total number of readings collected at each location, it indicates a lack of consistency in collection of the chemical samples of different locations. Measure |
