Experimental Design and Research Principles

Front

Engineers and scientists design experiments to answer specific questions or address problems.

Back

Experiments help in making decisions, identifying design criteria, comparing solutions, and testing final designs.

Front

Experimental design is a crucial part of the design process.

Back

It involves a logical progression of steps to define and focus the work.

Front

Analyze the Data

Back

The fifth step in experimental design where data collected from the experiment is examined to draw conclusions.

Front

Specific and Relevant Question Frames

Back

Essential for directing the course of the experiment effectively.

Front

Outcome of the experiment

Back

The data collected needs to support or refute the hypothesis.

Front

Importance of a well-designed experiment

Back

It addresses the hypothesis and identifies specific experimental details.

Front

Scientific evidence in hypothesis

Back

Supports the testable hypothesis and is based on research.

Front

Collect data and complete the data table.

Back

Include units and ensure data consistency through multiple trials.

Front

Synthesize and model data using graphs, charts, or figures.

Back

Use logical methods to represent data visually.

Front

Plotting variables on graphs

Back

Independent variable on the x-axis, dependent variable on the y-axis.
