Monitoring your readiness
7) To effectively plan and use your time wisely, it helps to think about what you know and do not know. For each of the following, rate how confident you are that you can successfully do that skill. Use the following descriptions to rate yourself:
5—I am extremely confident I can do this task.
4—I am somewhat confident I can do this task.
3—I am not sure how confident I am.
2—I am not very confident I can do this task.
1—I am definitely not confident I can do this task.
Skills Needed for In-Class Activity 3.E
| Skill or Concept: I can . . . | Questions to check your understanding | Rating from 1 to 5 |
| Use technology to create a histogram or dotplot. | 1, 4 | |
| Compare centers of distributions of a quantitative variable. | 2 | |
| Compare spread in distributions of a quantitative variable. | 3, 6 | |

Now use the ratings to get ready for your next in-class activity. If your rating is a 3 or below, you should get help with the material before class. Remember, your instructor is going to assume that you are confident with the material and will not take class time to answer questions about it.
Ways to get help:
- See your instructor before class for help.
- Ask your instructor for on-campus resources.
- Set up a study group with classmates so you can help each other.
- Work with a tutor.
