Lab-Aids: Variation - The Normal Distribution of the Characteristics of a Species Kit


Variation in species and normal distribution are brought to life as students use LAB-AIDS‚® exclusive Variation Profile Tubes. They gain experience in constructing visual graphs, histograms and linear graphs from data collected by the entire class. The idea that greater validity of information gathered from a large sample versus a smaller sample is illustrated beautifully by comparing class results in the Variation Profile Tubes to the student's own histograms and graphs. This is an excellent activity for introducing statistics in science. Continuous and discontinuous variation is explained in the activity as well as the normal distribution of the bell curve".
