Jordan counts how many red, blue, green, and yellow cars pass by in 10 minutes. Name two things Jordan should write at the top of his data table.
Think about what someone else would need to know to read the table correctly.

The school cafeteria wants to know which lunch students prefer. Which data collection method is best: guessing, asking students in a survey, or looking at the weather? Explain your choice.

The numbers are not very useful by themselves because they do not say what was counted. The student needs labels, a title, or categories to explain what the numbers mean. - 7
You are collecting data about how students get to school. Write four possible categories for your data table.

A class is measuring plant growth each Monday for four weeks. What should they record each time they measure the plant?

They should record the date, the plant height, and the unit of measurement. Recording the same information each time helps the data stay organized. - 10
Sam asks only his three best friends what game the class should play. Explain why this may not give a fair picture of what the whole class wants.

The following temperatures were recorded each day: Monday 70°F, Tuesday 72°F, Wednesday 71°F, Thursday 75°F, Friday 74°F. Make a table with two columns that would organize this data.
One column should tell when the data was collected, and the other should tell what was measured.
The table should have one column labeled "Day" and one column labeled "Temperature." The rows should list Monday 70°F, Tuesday 72°F, Wednesday 71°F, Thursday 75°F, and Friday 74°F. - 12
A teacher wants students to record how many pages they read each night for a week. Why is a table a good way to record this data?

Write one observation you could record while studying the weather outside. Then write one measurement you could record.
An observation can use your senses, while a measurement usually uses a tool.

A group is counting insects in the school garden. They find 7 ants, 2 butterflies, 5 beetles, and 1 ladybug. What title would be a good title for this data table?
