Determinate (Systematic) Error - Uncertainty that is inherent in the measurement devices (hard to read scales, etc.) - Usually caused by poorly or miscalibrated instruments. - There For instance, a thermometer dipped into a hot liquid to take a measurement causes the temperature of the liquid to cool slightly. Please upload a file larger than 100x100 pixels We are experiencing some problems, please try again. have a peek here After the cuttings were placed in the soil, errors may have occurred due to the amount of water that was fed to the plants.

Equipment limitations also cause errors if instruments are not calibrated properly or if an instrument is unable to take a measurement because of calibration limitations. If desired, these variations may be cause for closer examination, or they may be combined to find an average value. These pages illustrate one run through of calculations Another document will be about what these statistical quantities might tell us and how we might use this information to make certain decisions Q: Why are culture media sterilized before use?

It is possible to mistake an item with a variable value as an error. The system returned: (22) Invalid argument The remote host or network may be down. Physical variations (random) - It is always wise to obtain multiple measurements over the entire range being investigated. The idea here is to give you the formulae that are used to describe the precision of a set of data.

It is important to be able to distinguish between the items that have variable values and the items that have definite values when conducting an experiment. The adjustable reference quantity is varied until the difference is reduced to zero.
