How Many Single Father Households are in the United States?
While completing this activity, students will estimate the number of single father households in the United States by exploring Census Bureau data. They will calculate the mean, median, and mode of a random sample of ten states, evaluate the mean, and analyze the median.
CCSS.Math.Content.7.SP.A.2: Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.
Students will be able to identify the correct values in a table.
Students will be able to estimate the average of a set of numbers by calculating the mean.
Students will be able to calculate the measures of central tendency for a set of data.
Students will be able to evaluate the accuracy of the mean of a sample for a given population.
Instructions for Teachers
After a lesson on central tendency, students can complete this activity either individually or in groups. Ideally, students would be working in pairs so that they have the opportunity to discuss their findings. This activity should take approximately 10 minutes followed by a 5 minute class-wide discussion.
