To answer this question, we need to make sure we've read the text provided in the question: 

"Several students from Jones Middle School participated in a  race this weekend. The gym teacher at the school displayed the time, in minutes, it took each student to complete the race in the chart provided. "

Based on the information given, the unit of measurement used in this chart is minutes. 

The number of observations made represents the number of students that participated in the race.The chart shows how long it took each student to complete a  race. Each entry in the chart is how long it took each student to complete the race, so we can count up the number of entries to answer this question. 

If done correctly, you should have counted  entries; thus,  students participated in the race. 

To answer this question, we need to make sure we've read the text provided in the question: 

"Wrigley, a chocolate labradoodle, had a litter of puppies. During a veterinary appointment, each of the puppies were weighed, in pounds, and each weight was documented on the chart provided. "

To answer this question, we need to make sure we've read the text provided in the question: 

"Wrigley, a chocolate labradoodle, had a litter of puppies. During a veterinary appointment, each of the puppies were weighed, in pounds, and each weight was documented on the chart provided. "

Based on the information given, the unit of measurement used in this chart is pounds. 

The number of observations made represents the number of puppies in the litter whose weight was recorded.The chart shows the weight of each puppy, so we can count the entires to find the correct answer. 

If done correctly, you should have counted  entries; thus, puppies's weights were recorded. 

When we are given a graph or a chart that is labeled with a title, that is generally the best place to start when looking for what is being measured in a chart. This graph is labeled with "Hours Spent on Homework Per Week". Also, when we read the text before the question, we were told that, "a teacher decided to start tracking the amount of time her students spent on homework each week. The data is displayed in the histogram provided"; thus, hours spent on homework per week is the best answer choice. 

To answer this question correctly, we need to look at the histogram. The teacher is tracking hours that each student spent on homework per week; thus, the correct answer is hours. 

For this plot, the number of observations made represents the number of students that participated in the survey. Each bar goes up to a certain number of students, so we can add up the height of each bar to determine the number of observations that were made.

If done correctly,  we should have found that  students were surveyed. 

When we are given a graph or a chart that is labeled with a title, that is generally the best place to start when looking for what is being measured in a chart. This graph is labeled with "Money Earned Through Fundraiser". Also, when we read the text before the question, we were told that, "Mrs. Hobb's  grade class just completed a fundraiser to help fund their field trips for this school year. The money that the students sold is displayed in the histogram provided"; thus, money earned through the fundraiser is the best answer choice.
