An experimenter sets out to find out how many hours of sleep a dog needs in order to catch the highest number of balls without a bounce. To test this the experimenter uses 5 dogs in the experiment and allows each dog to sleep a predetermined amount of time: dog 1: 4 hrs, dog 2: 6 hrs, dog 3: 8 hours, dog 4: 12 hours, dog 5: 16 hours. If a dog sleeps of its own free, will it is normal for a dog to sleep for 8 hrs. After having the dogs establish these sleep patterns the experimenter through each dog 20 balls and recorded the number each one caught.
Dog1 5% Caught
Dog 2 15% caught
Dog3 50% caught
Dog 4 97% caught
Dog5 2% caught
What was the control group?
Write the conclusion for this experiment
Why do you think that dog #5 performed so poorly? How could you test this theory?
To determine the control group in this experiment, we need to identify the group that represents the standard or normal condition. In this case, since the experiment is investigating how sleep duration affects the number of balls caught, the control group would be the dog(s) that slept for the average or typical duration—8 hours.
The conclusion for this experiment would be made based on the data collected from the dogs' sleep patterns and their respective ability to catch balls. From the given results, it appears that different sleep durations have varying effects on dogs' catching abilities. Dogs that slept for durations closer to the average (8 hours) tended to catch more balls, with dog 3 (sleeping 8 hours) catching the highest percentage (50%). However, the data also suggests that excessively long sleep durations, like in the case of dog 4 (12 hours) and dog 5 (16 hours), had a negative impact on catching performance.
Regarding dog #5 performing poorly, it is possible that excessive sleep negatively affected its alertness, energy level, or focus. To test this theory, one could design an experiment where dog #5 is given a different sleep duration closer to the average, such as 8 hours. Then, its catching performance with this changed sleep pattern can be compared to its previous performance. This would help evaluate if the amount of sleep was the contributing factor to dog #5's poor performance or if there were other factors at play.
The control group in this experiment would be the dog that slept for the recommended 8 hours, which in this case would be Dog 3.
The conclusion of this experiment is that the amount of sleep a dog gets can significantly influence its ability to catch balls without a bounce. Based on the results, it can be observed that dogs who slept for longer durations (Dog 4) caught a higher percentage of balls, while dogs who slept for shorter durations (Dog 1 and Dog 5) caught significantly fewer balls.
There are a few possible reasons why Dog 5 may have performed poorly. One potential reason could be that 16 hours of sleep is excessive for a dog, resulting in grogginess, reduced alertness, and slower reflexes. Another reason could be that Dog 5 might have had a different sleep quality or sleep disorder affecting its cognitive and physical abilities.
To test these theories, additional experiments could be conducted where Dog 5's sleep duration is adjusted to a more typical range, such as 8 hours, and its performance in catching balls is re-evaluated. Furthermore, monitoring Dog 5's sleep patterns and potentially analyzing its sleep quality through methods like sleep monitoring devices or observing its behavior during sleep could provide further insights into the connection between sleep and performance.
