This activity will help you meet these educational goals:

You will use mathematical representations of phenomena to describe and support claims and explanations.
You will analyze data using tools and models in order to make valid and reliable scientific claims.
You will apply concepts of statistics to scientific questions and problems, using digital tools when feasible.
Directions
Read the instructions for this self-checked activity. Type in your response to each question, and check your answers. At the end of the activity, write a brief evaluation of your work.
Activity
In this activity, you’ll analyze and interpret data about a population. A scientist has been monitoring the height of a small population of wild sheep for 30 years. He monitored 200 adult male sheep from each year, and then broke down their height into ranges. Study the data in the chart, and then answer the questions that follow.

Part A
Question
Using the data in the table, make a bar graph that shows the distribution of height for the sheep both 30 years ago and today.

Part B
The researcher thinks the changes in data are a result of selection. Do you think directional, disruptive, or stabilizing selection is occurring? How does your data support this conclusion?

Part C
What percentage of sheep had a body height of 1.2 meters or more 30 years ago? How does it differ from the present data? Does this data support your argument regarding the type of selection occurring?

Part D
The researcher also collected height data from 200 female sheep during both years but didn’t notice a significant difference in height. What could this data suggest?
