Unit 1 Exp Design TJB Flashcards
Testable question
A testable question is a question that can be answered by designing and conducting an experiment.
Non-testable question
Questions that cannot be answered by direct observations or by evidence gathered through experimental inquiries
Quantitative
Data that can be counted or measured in numerical values
Qualitative
Non numerical data like text, video, or audio to understand concepts, opinions, or experiences
Trials
Trials are repetitions of the same procedure.
Observations
Using the senses to gather information about an object or event.
Data
facts and statistics collected together for reference or analysis
Empirical evidence
Empirical evidence is information acquired by observation or experimentation.
Models in science
A scientific model is where scientists represent something in the real world in a way that makes it easier to understand, or make predictions.
Analogy
Analogies are a comparison of the similarities between two concepts.
Prototype
A prototype is an original model constructed to include all the technical characteristics and performances of the new product.
Hypothesis
A hypothesis is a concept or idea that you test through research and experiments.
Variable
Variables are anything that can change or be changed within an experiment.
Procedure
A procedure is a listing of what specifically was done in the laboratory during an experiment, step by step.
Precision
Precision refers to how close measurements of the same item are to each other.
Accuracy
Accuracy refers to how close a measurement is to the true or accepted value.
Scientific method
The scientific method is the process of objectively establishing facts through testing and experimentation.
control
A control is an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured.
Constant
A constant is the part that doesn’t change during the experiment.
Predict
To say or estimate that a specified thing will happen in the future or will be a consequence of something.
Infer
To deduce or conclude information from evidence and reasoning rather than from explicit statements.
Independent variable
The independent variable is the variable that stands alone and isn’t changed by the other variables you are trying to measure
Dependent variable
The dependent variable is what you measure in the experiment and what is affected during the experiment.
Manipulated variable
The manipulated variable is the variable that you control and change based on the experiment.
Responding variable
The responding variable is what changes as a result of the manipulated variable.
Sample size
The sample size is the number of participants or observations included in a study.
Validity
Validity refers to how accurately a method measures what it is intended to measure.
Trends in Data
A trend in data analysis describes the general change in a variable with time.
Correlation
A correlation shows a connection between a factor and an outcome.
Variability
Variability is the degree to which data in a set varies, or how much difference there is in a single set of data.
Mass
Mass is a measurement that refers to the amount of matter that makes up an object.
Volume
Volume is the amount of space occupied by a sample of matter.
Weight
Weight is a measurement for the force that gravity applies to an object.
Percent
One part of every 100, or the specified amount of something divided by 100.
Rate
How much a certain quantity changes with respect to another quantity that is also changing.
Ratio
The relationship or comparison between two numbers of the same unit to check how much bigger is one number than the other one.
Line graph
A line graph is a graph that uses lines to connect individual data points. Often used to show changes over time.
Bart Graph
A bar graph is a specific way of representing data using rectangular bars in which the length of each bar is proportional to the value it represents.
Pie graph
A pie chart is a type of graph representing data in a circular form, with each slice of the circle representing a fraction or proportionate part of the whole.
Scaterplot
A scatterplot uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.
Claim
A statement or conclusion that answers the original question/problem.
Evidence
the available body of facts or information indicating whether a belief or proposition is true or valid.
Reason
The ability to recognize and understand the scientific method, concepts, processes, and applications used in the pursuit of knowledge.
Theory
an idea or set of ideas that is intended to explain facts or events.
Bias
Any tendency which prevents unprejudiced consideration of a question .
