The reliability of data is a critical issue in decision-making for practitioners in the school. Percent Agreement and Cohen's kappa are the two most widely reported indices of inter-rater reliability, however, a recent Monte Carlo study on the reliability of multi-category scales found other indices to be more trustworthy given the type of data…

Describes data analysis activities for grades three through six using unshelled peanuts. Includes two reproducible student worksheets. (MKR)

Data on sex differences in rote-counting ability for 4722 first-grade children are presented. How different data-gathering methods and different statistical treatments of the data can yield differing results are indicated. (MNS)

Introduces a unit on data analysis which would not only satisfy elementary statistics requirements but also involve students in a long-term mathematics project in a meaningful and relevant way. Addresses the mathematical concepts of measurement, graphing, and computation. (ASK)

Four activities are described which focus on consumer awareness and judgment using data collection and judgment skills involving data from footwear. Worksheets for data collection and activities at home and at school are included. A set of ratings of sneakers from "Consumer Reports" magazine is provided. (CW)

Describes 4 activities for levels K-2, 3-5, 4-6, and 6-8 and a family activity that asks students to describe their community; use coordinates to represent the 4 voyages of Columbus; write a story based on a line graph of Lewis and Clark's expedition; determine serving sizes for astronauts in space; and investigate different modes of…

Describes four activities for grade levels K-3, 4-5, and 6-8 and for the family that explore statistical concepts using a manipulative familiar to students-SKITTLES candies.
