Data Analysis 2

Featured Topic:   Data Analysis

Students are encouraged to collect real, meaningful data, organize that data and analyze the data to draw conclusions and explain what they have learned. There are many opportunities to incorporate data collection experiences within the school day.

Question of the Day

Capitalize on student interest by creating a daily data collection activity. Mrs. Soranno's kindergarten students move their name to answer the question of the day. Evidently the class is evenly split on whether or not they like mustard.

Use a variety of data organization tools: tally chart, Venn Diagram, clothespin graph, bar graph, pictograph, etc. to help students learn to organize and interpret data in these different representations.

  • See Winter Data Collection Activities for some suggested data collection questions and topics
  • Teachers of older students sometimes assign students the job of creating the question of the day and reporting the results to the class.

Clothespin Graphs

Write each student's name on a clothespin. A piece of foam core board or laminated oak tag makes a great two-choice (Yes/No) graph board. Students simply affix the clothespin to the correct side to indicate their response. Students can easily "see" the results and count to verify the outcome.

  • Use this method to record the results of informal classroom surveys:
    • Literature: Which character do you like best? What do you think the character will do next? Which version of the story do you prefer?
    • Daily Routines: Are you buying lunch or did you bring lunch? Present or Absent?
  • Ask students to report the results of who won two-player games so that the class can analyze the fairness of the games.

Seasonal Data Collection Activities

Seasonal activities, field trips and parties create opportunities for data collection that students truly enjoy. Whether they are planning for a party or a field trip, students enjoy having some input into the experience and seeing how their classmates vote as well.

Morning Routines

Weather results provide great data for student analysis. Students can easily compare months to see which month has more rain, snow, sun, clouds, etc.

Teachers can informally generate questions based on a quick glance at the weather chart. These questions should also ask students to predict what the upcoming weather will be like: will we have more sunny or cloudy days? more rainy or snowy days?

Finally, students can reflect on the seasons and see similarities in those months in terms of sun, rain/snow, wind, etc. Does March really come in like a lion and go out like a lamb?

See Morning Math Routines and Morning Math Routines: Photo Gallery for pictures and descriptions of these data collection activities.

More Data Collection Activities

Count in a Minute: First graders at Flynn School in Perth Amboy, NJ, created a large line plot of how high they could count in a minute. Student pairs worked together to time and count then post the results on the class graph.

Heads-Tails: a Probability Experiment Challenge students to analyze the fairness of this game that uses a single coin. Student A wins a point if the toss is the same as the last toss and Student B wins a point if the toss is different. Is the game fair?
