Presenting Scientific Data

Organizing DataScientists can organize their data by using data

table and graphs

Data tablesRelates the manipulated and responding

variables

Bar Graphs

Often used to compare a set of measurements

Circle Graphs

Shows a part or share of something (often as percents) compared to the whole

Line graphs

Shows changes that occur in related variables

Manipulated on x axis

Responding on y axis

Direct Proportion

when relationship of the two is constant

When one increases, the other increases too. Graph is a straight line.

Inverse Proportion

when relationship of the two is opposite

When one increases, the other decreases.

Communicating Data

Scientists can communicate results by writing in scientific journals, speaking at conferences, or through conversations, e-mails, and web sites.

Scientists also invite feedback from those peers. Peer review encourages comments, suggestions,

questions, and criticism from other scientists. Peer review can also determine if data were

reported accurately and honestly.
