CW #9 : MAKING DATA TABLES AND GRAPHS

Part A: Teacher Example

Problem:

Data and Results: (leave at least 8 lines to write your

Data table)

Graph

Step 1: figure

Out the problem or question

Is the sea otter population increasing, decreasing

Or remaining steady?

CW #9 : MAKING DATA TABLES AND GRAPHS Part A: Sea Otters

Problem: Is the sea otter population increasing, decreasing or remaining steady?

Step 1: figure

Out the problem or question

In year one of the study (1962) they counted 46 otters. Eight years later the count was 42. In 1982 the count was 35. Ten years later it dropped to 30. At last count in 2002, the count of was 26.
