This statistical study was carried out on the Tampa Bay area in an effort to establish some basic relationships between levels of chlorophyl A and various environmental factors. Several statistical analyses were carried out. It was decided to use original data rather than averages over several months. It was felt that this would give us more reliable results. At the outset, the study centered around the use of data from only three months during the year; namely, February, June and October. It was felt that these months would be representative of the seasonal difference. Later, all months of the year were used in order to obtain more general relationships. The statistical analysis performed assumes that the data is normally distributed. It was felt that as a first study the assumption would not be of great consequence. Analysis of variance was carried out to provide some indication of where the variation in the data lay. Statistical correlations were also carried out and multiple regressions were performed.
