Rside-Human A&P Scientific Method
Specific method by which scientists gain knowledge about the world.
Terms in this set (92)
In an experiment, the standard that is used for comparison, it is never exposed to the experimental factor.
The experimental factor that is manipulated; the variable whose effect is being studied
A factor in which its value is reliant on the independent variable.
A group within an experiment that is exposed to the independent variable.
A question that inquires about the world and its processes.
The idea of replicating an experiment to determine whether or not the same results can be found again.
Summarizes the important parts of your experiment and is a discussion of what the data, patterns, and relationships mean
Anything that could change in an experiment and affect the results/outcome of the investigation
A set sequence of steps to complete an experiment
The scientific method is a specific method by which scientists gain knowledge about the world.
Large sample size:
This ensures that results are valid. Many repetitions could be done if sample size is not sufficient.
Replicate groups that are exposed to the same conditions in an experiment
Organizes data into rows and columns
Information recorded to provide more data toward answering the hypothesis
Hypothesis written as an "if/then" statement
Errors that may occur in the trial of an experimental design
These are factors that are held constant throughout the experiment. these include all factors except the experimental variable.
Observation of a quality, trait, or value judgment, described without using numbers.
Observation of a measurement stated with a numeric value.
A document written to outline and analyze a scientific lab experiment.
A set of assumptions, propositions, or
accepted facts that attempt to provide a plausible or rational explanation of cause and effect relationship among a group of observed phenomenon.
This can also be referred to as the independent or manipulative variable. It is the factor being tested and there should only be ONE experimental variable in experiment.
Measures the number of individual samples measured or observations used in a survey or experiment
Use of one or more of the senses-sight, hearing, touch, smell, and sometimes taste- to gather information
The reason for which something is done or created or for which something exists
Repeating the experiment to find the most accurate results
What could have been present to change the results of the experiment. Example: viruses, humidity, etc
An investigation done in order to make a discovery or test a hypothesis
An educated guess about what is going to happen
Information gathered during an experiment
Estimate the nature, quality, ability of significance of your experiment
An effect, or outcome of the experiment
Briefly expresses the main idea and relevant details of your experiment and results
A change that is a result or consequence of an action or other cause; ex. The effect of sugar amounts on the rising of bread.
To devise or develop as a method; ex. To formulate a hypothesis.
The analysis of the results of the experiment does not support the hypothesis; resulting in refining the hypothesis and starting the method over again.
Characteristics of a valid scientific experiment
Data that seems to be inconsistent to the pattern established by additional data
Visual representation of the relationship between two different variables
ex: bar graph, line graph
A brief overview of the investigation
Data that seems to be inconsistent or contradictory to the pattern established by additional data
Making sense of observations and data collected during an experiment using appropriate measures of central tendency (mean, median, mode, range) and by
looking at patterns and relationships between the
independent variable and the dependent variable
A conclusion reached on the basis of evidence and reasoning
A scientific process that involves the systematic and careful collection of data.
Combining several pieces of information to make an inference
A person who uses the scientific method to discover new knowledge.
Which letter style combines efficiency with an attractive page layout?
The extent to which a test measures or predicts what it is supposed to.
The extent to which a test yields consistent results
The traits or properties of a living or non-living object.
Not good enough; not correct
Factor in an experiment that a scientist wants to observe, which may change in response to the manipulated variable; also known as a dependent variable
Organize and carry out
A change or difference in condition, amount, or level, typically with certain limits.
Is the sum of a list of numbers divided by the number of numbers in the list.
A question proposed for solution.
The process of making sense of numerical data that has been collected, analyzed or presented.
The determination or estimation of ratio of quantities.
These are variables that are changed on purpose in the experiment. It is what you are testing. Also known as the independent variable.
Anomalous Data (outliers)
data that seems to be inconsistent or contradictory to the pattern established by additional data
a type of graph used for descriptive data that comes from research questions asking about variables that will be counted
a constant variable that is part of the experiment that is not being tested and is used for comparison
the method used to measure the dependent variable; the method used to describe the independent variable when testing various products
a graphic representation using symbols interconnected with lines, of the successive steps, in a procedure or system
PROCEDURE that TESTS a HYPOTHESIS by collecting information under controlled conditions
terms used in a science or art; study of nomenclature
a collection of organized data that allows access, retrieval, and use of data
The number that separates the higher half of data from the lower half. eg. 4,4,4,5,8,9,9 - median=6
The number or data that appears the most frequently in a set. eg, 4,4,4,5,8,9,9 - Mode=4
The system or practice of how something is done. In experimental design, the methodology refers to the "how" or process in which the experiment took place.
Analysis of data set in order to devise an interpretation.
It provides a basis for comparing with the experimental group.
Presenting a project to an audience about your experiment.
Items/supplies needed during the experiment.
Having a sound basis in logic or fact that is reasonable.
Grouping similar items by common traits on data or within the experiment.
Generalising statement based off of repeated observational experiments. Does not explain the 'why', and can be proven to change under different circumstances.
Data produced from an experiment or observation.
Scientists performing an experiment influence the results in their favour, or by experimental error in which failure arises due to not considering all the possible variables.
A result without expected content or effect, proposed result is absent.
A hypothesis where there is no observed difference being due to sampling of experimental error.
The condition of being protected from or unlikely to cause danger, risk, or injury.
Make sure or demonstrate that something is true, accurate, or justified.
The action of putting something into motion, implementing a process
Estimate, measure, or note the similarity or dissimilarity between
A small part or amount intended to show what the whole is like
A fact that contributes to an outcome
Observe, study, or make a detailed and systematic examination, in order to establish facts and reach new conclusions.
To examine carefully; study closely
A testable prediction, often implied by a theory
A statement of what will happen next in a sequence of events.
A scientific process that involves the systematic and careful collection of data.
