These results definately show us some insights into our data. We see that the settling data in one experiment will not be the same as in the next experiment (when all variables of the experiment remain the same). From the data, it appears that there is no significant difference from having the turbidimeter position at the top or at the bottom of the column, except for the slight increase in the max standard deviation of the effluent settling turbidity, and the increase in range of effluent turbidity standard deviation values. For example, the standard deviation values at the end of the settling time in the top position experiment ranges from 2 to 12, whereas the range of the standard deviation values at the end of the settling time in the bottom position experiment ranges from 5 to 15. This difference in standard deviation is
The effluent turbidity data for each run was time averaged over a 60 second interval (Figure 3, 4, 5) to get a smoother curve. Graphing the raw effluent turbidity data is noisy and hard to make any clear conclusions. From these graphs, we can determine that the number run in a set of runs does not affect the settling turbidity. There is no trend between the number run in a set and the settling turbidity. This is good news for our research, because most of the data from last semester was collected during a large experiment that involved 30 or more runs. Now that we know that the number of runs does not affect the settling turbidity, we can conclude that our data from each run in our large experiments from last semester are not affected by the other runs in the experiment.
