Activity 4: Who's got the quickest REACTION TIME? (GLEs: 34, 36, 39)
CC: Have the students go to the website http://faculty.washington.edu/chudler/chreflex.html and read through different reaction time activities. Have them design their own simple activity using the ones on the website or the meter stick drop-and-catch activity.
CC: With this data, have students create a histogram comparing class data of the number of students that have average reaction times in the different intervals:
Introduction and information about histograms. This applet is designed to teach students how bin widths (or the number of bins) affect a histogram. The students can manipulate the bin widths to see how the graph is affected.

CC: Next, instruct the students to determine the percent or fraction of students in each interval and create a circle graph representing the numbers and percent of the class in each interval.
MS Excel will allow students to create circle graphs. Students can create circle graphs at Create A Graph. |
