Experiments and Variables
This affects the reliability of the conclusions you draw from the scientific method.
What is the application, or the way you apply the scientific method?
One way to organize data or information from an experiment is by using this method.
What is construct a table, which contains spaces organized into horizontal rows and vertical columns?
True or false? Experimentation is only used in the field of science.
What is false; experimentation is used in many fields, including marketing?
This graph compares the relative sizes of two sets of data.
What is a double bar graph?
This is a way to record lots of information/data in a visually interesting format that is concise, clear, and easy to read.
What is an infographic?
This scientist’s experiments still came to faulty conclusions even though he applied the scientific method.
Who is Percival Lowell?
Fill in the blank: every column and table should have a ______.
What is title that explains the information in each column and the entire table; it should be brief and capitalized like a proper title?
Experiments in which information about the test is kept from the participants to reduce bias are called ______.
What are blind experiments/studies?
This gives you information about a graph so you can better read it.
What is a legend?
Doing this helps make the scientific method most useful to answer a question.
What is removing unwanted or undesirable variables so your results are as accurate as possible?
This is an aspect of an experiment that changes during the course of an experiment.
What is an experimental variable?
Most scientists do this in order to develop a good conclusion about something.
What is perform several experiments in order to develop a good conclusion about something?
This is another way to improve your experiment and remove bias.
What is set up a control group or a control trial?
To read a bar graph correctly you must do this first.
What is you must look at the information given around the graph first, like the title, the axes, and the legend.
This is the variable in the experiment that is being tested.
What is the desired variable?
This helps you to avoid flaws in your scientific work/experiments.
What is identifying variables in an experiment?
This is the variable part of an experiment to which all others will be compared.
What is the control (of an experiment)?
These are experiments in which neither the experimenters nor the participants know the objects' identities in the setup.
What are double-blind experiments/studies?
This part of the bar graph lets you know which 2 parameters are being compared.
What are axes?
Complete this sentence: Not all experimental variables are ____.
What is bad?
This is used to compare items or show relationships between groups, such as how something changes over time. It’s a fast way to show big differences in your data, like when presenting information from surveys.
What is a bar graph?
This type of variable or data is dependent on the opinions of people.
What is subjective variable or data, like taste?
This type of graph is used to report data when you want to easily visualize the size of parts of a whole.
What is a circle graph or a pie chart?
This is the reason why a scientist may want to include some variables in their experiments.
What is to learn something by comparing the experimental results to the variables?
The bar graph consists of these two types of variables.
What are the independent variable (horizontal x-axis) and dependent variable (vertical y-axis)?
True or false? All experiments have subjective data or variables.
What is false; some experiments don’t have subjective variables?
These are marks you make in groups of 5 that make it easier to count items.
What are tally marks?
This is the conclusion you can make after the egg and water experiment?
What is salt water is denser than pure water?
This type of variable is NOT affected by the other variable.
What is the independent (x-axis) variable?
This type of variable or data does not require the trouble of setting up a blind or double-blind experiment.
What are objective data or variables?
This is how circle graphs are similar to bar graphs.
What is they both make data easier to view so conclusions are more easily reached?
To identify the variables in an experiment, it is best to think about this.
What is changing in your experiment?
This is where you look in your experiment to create evenly spaced numbers along the vertical axis (the dependent variable).
What is look at the data you collected?
It records individual data as points on a graph, report trends in what is being studied, help us see changes between any 2 points, identify trends from certain periods.
What are line graphs?
This word means to change or alter or cause to be different from something else.
What is vary?
This is typical of how scientists learn what they want to learn about creation.
What is they look at a single variable’s effect in many different experiments, hoping they can draw some general conclusions after several effects are studied?
Line graphs and bar graphs can be compared in these ways.
What is line graphs are best used to find trends in information; bar graphs can be used to exhibit data?
This is what you should do when you want to design a good experiment.
What is you should always reduce the number of experimental variables that are not a necessary part of the experiment?
You first need to identify these things before making a line graph.
What is the information that will go on each axis?
These documents help us to more easily record data.
What are graphs and tables?
