Scientific Method: Data Collection

Data Data – the results of the experiment Should: be written on a chart or graph clearly show how they were measured

Review: Types of Data 2 types of data collected: Qualitative data includes descriptions or sights, sounds, smells, and textures Her shirt is green, The room is cold, The class is loud Quantitative data are expressed in numbers and include records of time, temperature, mass, distance, and volume It is 75 degrees F, He is 6 feet tall, There are 32 chairs in the classroom

Recording Data During the experiment, record data in a data table Should include Title Heading for each column and row Units that were used

Graphing Data Title Label for each axis including units of measurement Choose an appropriate scale Include a key
