1 answer:
Of the steps included in the scientific method, Shameka is performing step five, which is to<u> test your hypothesis by performing an experiment</u>.
The scientific method is the globally accepted process by which to make scientific claims. This method includes seven steps which are:
- Ask a question
- Do research
- Create a hypothesis
- Design an experiment to test the hypothesis
- Perform the experiment
- Study the results and make a conclusion
- Communicate the results to your peers.
The question states that Shameka is <u>gathering samples from nearby water sources</u>, therefore she is in the process of testing her hypothesis through experimentation, which corresponds to step 5 of the scientific design.

Answer:
This question is incomplete because of the absence of the data referred to in the question
Explanation:
This question is incomplete but the data referred to in the question is attached below
In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.
From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)
Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17
Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13
Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below
The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm
The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm
