Designing Data Case Study

When Chad begins a conversation with Sally he is displaying that he understands the value in defining and classifying your data categories. He understands that if one has not developed a clear definition then participates maybe responding in any way.  This means that their response could be incorrect for the data he desires to obtain. He wants his data to be a true picture of the question that was proposed.

Students understand that when you represent given data in a chart or graph that it needs to be accurate. Therefore, their questions needs to be made clear to all participates, so that they can responded in the correct manner.

I enjoyed reading the Nadia’s study and thought that the teacher did a wonderful job questioning the students about their survey questions. I actually got a kick out of the sports question. Students are learning that they must have a well-defined question if they want to receive accurate data. Luke displays his understanding of survey questions when he states the difference between to moving questions. This group gave a clear definition of moving by asking the question “how many times have you moved from house to house with all of your belongings?” One group gave a clear question of “how many languages do you speak fluently?” Then they defined what they meant by fluently.

In Andrea’s case study they should say “how many people are in your family that live in your house?” As far as the questions about “how many houses are on your street, I am not sure what exactly the students are looking for and how you would redefine it. That would be a hard question to answer.

Natasha is wanting to know how many states the person being interviewed have visited and they were intentional about being there.  She may could word it like this “how many states have you visited where you spent your vacation or visited family members? She is looking to know how many states her participates have actually spent a given amount of time in. The survey question that they decide on does not reflect the information that she is looking to gather. I think that the teacher in these studies are doing an excellent job of getting their students to think about what their survey questions are really asking. They ask a lot of open ended questions that get their students thinking and questioning others.
