Results

Data was recorded each day (Table 1 and 2) and at the end of the experiment an ANOVA (analysis of variance) test was performed to see of there was a difference in the measurements or if it occurred out of chance, thus it will explain if the data supports the hypothesis.

Observed results in Table 1 shows an increase in food consumption when the amount of light increased. A p-value of 0.34 for average consumed food (Table 3) indicates no significant difference between photoperiod change and consumed food since it is greater than 0.05. Observed results in Table 2 do not show a significant increase or decrease in water consumption most likely do to frequent water leaks throughout the experiment. A p-value of 0.08 for average consumed water (Table 4) indicates no significant difference between photoperiod and consumed water.

Table 1: Average Food Consumption (g)
Photoperiod	H1	H2	H3
12:12 (Control)	3.8	2.73	2.43
9:15	4.77	2.73	3.94
6:18	4.86	3.25	5.2
12:12 (Control)	2.99	2.34	3.53
15:9	3.68	5.7	6.64
18:6	3.03	3.56	3.55

Table 1: Average food consumption for hamster 1, 2, and 3. The amount of food consumed in the three days of each photoperiod was averaged for each hamster.

Table 2: Average Water Consumption (ml)
Photoperiod	H1	H2	H3
12:12 (Control)	57.5	20	45
9:15	13.7	14.7	16.3
6:18	16	6.67	18.3

Table 2: Average water consumption for hamster 1, 2, and 3. The amount of water consumed in the three days of each photoperiod was averaged for each hamster.

Table 3: A p-value for the columns section represents the variance of consumed food compared to the photoperiods. A p-value of 0.34 shows there is no significant difference between photoperiod change and consumed food since the p-value is much greater than 0.05.

Table 4: A p-value for the columns section represents the variance of consumed water compared  to the photoperiods. Since the p-value is 0.08 and greater than 0.05, it shows that there is no significant difference of consumed water compared to the change in photoperiods.
