... areas of sparse vegetation can be misclassified if too much background-soil spectral response is present(Huete et al., 1994). Strategies to remove the soil background effects can be undertaken by using a tasselled cap transformation(Kauth and Thomas, 1976). This method, which creates a "Soil Brightness Index"(SBI), can be plotted to obtain an improved discrimination between the background soil spectra and vegetation.  2, record 1, English, - soil%20brightness%20index

A negative discrimination index is most likely to occur with an item that covers complex material written in such a way that it is possible to select the correct response without any real understanding of what is being assessed. A poor student may make a guess, select that response, and come up with the correct answer. Good students may be suspicious of a question that looks too easy, may take the harder path to solving the problem, read too much into the question, and may end up being less successful than those who guess.  1, record 2, English, - negative%20discrimination
