Data Management Test

Hi Grade 5s,

Here is your study guide for our test on Data Management.

Make sure you know how to:


• read and answer questions about bar graphs, line graphs, and circle graphs


• find the mean from data (add all the numbers, divide by amount of numbers added)


• find the mode (which number occurs most frequently)


• create a bar graph


• create a line graph


• arrange data into intervals


• explain why a jagged line is used in a line graph


• recognize bias in two graphs


• explain what a sample is, and why a biased sample would be used


Remember, you can always post your questions here.

See you tomorrow!
