What do you call the information gathered during experiments?
Data
– the facts, figures, and other evidence gathered through observations. ♦ Data Analysis- the process of interpreting the meaning of the data collected in. an experiment, finding patterns in the data, and thinking about what the patterns mean.
Which two methods do scientists use to gather information?
Scientists can gather their data by
observing the natural world, performing an experiment in a laboratory, or by running a model
. Scientists decide what strategy to use, often combining strategies. Then they plan a procedure and gather their data.
Which variable in an experiment does the person doing the experiment change?
The independent variable
is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.

- Analyze the results and draw a conclusion. …
- Present the findings.
How do we write a hypothesis?
- Don’t just choose a topic randomly. Find something that interests you.
- Keep it clear and to the point.
- Use your research to guide you.
- Always clearly define your variables.
- Write it as an if-then statement. If this, then that is the expected outcome.
How do scientists use the evidence they gather?
Scientists answer questions by gathering and evaluating evidence. One way scientists gather evidence is
through firsthand observation
; however, sometimes scientists ask questions about things that are not immediately observable.
How do professionals gather information on natural science?
Conference papers, dissertations, interviews, laboratory notebooks
, patents, a study reported in a journal article, a survey reported in a journal article, and technical reports.
How do you control variables in an experiment?
Variables may be
controlled directly by holding them constant throughout a study
(e.g., by controlling the room temperature in an experiment), or they may be controlled indirectly through methods like randomization or statistical control (e.g., to account for participant characteristics like age in statistical tests).
How many variables should an experiment test at a time?
An experiment should only test
one variable
at a time, which is called the independent variable.
What is the importance of variables in an experiment?
Variables are an important part of an eye tracking experiment. A variable is
anything that can change or be changed
. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.
What are the 4 types of observation?
- Controlled Observations.
- Naturalistic Observations.
- Participant Observations.
How do you collect data through observations?
»
Recording sheets and checklists
are the most standardized way of collecting observation data and include both preset questions and responses. These forms are typically used for collecting data that can be easily described in advance (e.g., topics that might be covered in an HIV prevention lesson).
