Assignment ExampleI will fake an aquarium with water, a total of five. I will prepare first 5 various water samples with varying degrees of dissolved oxygen 0, 2, 6, 12, 18 ppm. Then I will put in several fish in each of the 5 samples of water, perhaps 15 each and count the fish that will stay alive in it after 6 hours or so.The in open variable is the core of dissolved oxygen in the water because it does not depend on any factor and it is the one being manipulated for the experiment. The dependent variable is the number of fish because it depends on how much dissolved oxygen is in the water.The control chemical group is the one which is marked 18ppm, assuming that this is the average amount of dissolved oxygen in water. It depends on the average value of dissolved oxygen in water and that should be the control group. The purpose of the control group is to serve as the basis against which other experimental data will be compared.6. (1 point) What type of graph would be appropriate for this data set? wherefore? See p. 18-19 and the two types of graphs. Dont lead that the x-axis (horizontal) represents values for the independent variable (the factor you change or that you want to see what effect it has on a precise outcome) and the y-axis (vertical) are values for the dependent variable (the factor that you predict will change).7. (2 points) Graph the data from Table 2. Explain the reason for the type of graph you selected and dont forget to include a title, labels for the x-axis and y-axis (include the units). You may submit the graph as an Excel or other attachment.5. A local grocery store was holding a contest to see who could most closely guess the number of pennies inside a large jar.
