Question

1. a scientist is making observations about the growth of chimpanzees raised in captivity compared to the growth of chimpanzees raised in the wild. make a t - chart of 2 examples of qualitative data and 2 examples of quantitative data that the scientist could record.
2. in order to draw a meaningful conclusion from an experiment, what are 2 - 3 things a scientist should include or reference in his/her conclusion?
3. a scientist grows tomatoes in greenhouses that differ only in the amount of carbon dioxide in the air. he determines the weight of tomatoes produced by plants in each greenhouse, and compares them to each other and to tomatoes grown in air with a natural, unaltered amount of carbon dioxide. is this a controlled experiment? why or why not?
4. a group of scientists decide to post their research results on the internet instead of publishing in a scientific journal. what part of the scientific process have they skipped and why does it matter?

Explanation:

14.

Step1: Define qualitative data

Qualitative data is non - numerical, descriptive.

Step2: Provide qualitative examples

• Fur texture (smooth or rough)
• Social behavior (solitary or social)

Step3: Define quantitative data

Quantitative data is numerical.

Step4: Provide quantitative examples

• Height in centimeters
• Weight in kilograms

Qualitative Data	Quantitative Data
Social behavior	Weight in kilograms

Step1: Consider hypothesis

A scientist should refer to the original hypothesis to show if it was supported or rejected.

Step2: Mention data

Data collected during the experiment should be summarized, including mean, median, etc. if applicable.

Step3: Acknowledge limitations

Any limitations of the experiment (e.g., small sample size, measurement errors) should be mentioned.

Step1: Recall controlled experiment definition

A controlled experiment has one variable changed (independent variable) while others are kept constant.

Step2: Analyze the tomato experiment

Here, the amount of carbon dioxide is the independent variable, and other factors in the greenhouses are kept the same. There is also a control group (tomatoes grown in natural carbon - dioxide level).

Answer:

• Refer to the hypothesis.
• Summarize the data.
• Acknowledge the limitations.
