A class of 4th grade students is learning about different types of rocks. They weighed some samples of rocks that were about the same size and recorded the data. Use the data tables to compare the weights of the rock samples. Left Data Table: A data table titled Coquina. The two headings are Weight and Number of Samples. The weights are 1, 2.25, and 3.5. Beside 1 is the number 1. Beside 2.25 is the number 2. Beside 3.5 is the number 2. Right Data Table: A data table titled Sandstone. The two headings are Weight and Number of Samples. The weights are 1.5, 2.5, and 3.5. Beside 1.5 is the number 2. Beside 2.5 is the number 1. Beside 3 is the number 4. Select the statement that is true about the data tables. The median for the Coquina data set is 3.5. The median for the Sandstone data set is 1. The Coquina data set has 2 modes. The Sandstone data set has no mode.
