Marissa Burgess PHY 1110 Professor Ekwue Lab 1 Assignment 1 1 What patterns do you observe based on the information in Table 4 The variables have a positive correlation For example as one increases the other does as well 2 Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water As the amount of dissolved oxygen is increased the fish will increase too 3 What would your experimental approach be to test this hypothesis My experimental approach to assess this hypothesis would be to control the amount of dissolved oxygen in a homemade pond and observe if the fish increase or not 4 What would be the independent and dependent variables Independent variables dissolved oxygen Dependent variables observed fish 5 What would be your control My control would be the makeshift pond that I create 6 What type of graph would be appropriate for this data set Why The most appropriate graph for this data set would be a line graph because the variables would fit well on the axes 7 Graph the data from Table 4 Fish Population and Dissolved Oxygen Marissa Burgess PHY 1110 Professor Ekwue 16 14 12 10 8 6 4 2 0 0 2 4 6 8 10 12 14 16 18 20 8 Interpret the data from the graph you made in Question 7 The data from the graph I made in Question 7 shows that the fish increase as the dissolved oxygen increases
