Answers

1
What is a discontinuous variable?
Take values like depth and connect
Take values like time and connect
Certain values and do not overlap
Any value that goes on a continuous scale
2
What is the meaning of quantitative data?
Descriptive data about a variable
Numbers found from comments of individuals
Numerical data that gives the quantity, amount of range of a variable
Numerical Data that gives descriptive data on what is being tested
3
How do you calculate percent change?
Initial+final/final * 100
Initial-final/final * 100
Find+initial/initial * 100
Find-initial/initial * 100
4

Organism
Release species
Safety
Average
5
What is considered for a statement to be a law?
Turn it to legislation to have it passed
Examine hypothesis, follow line of reasoning & then create theory
Have theory declined and turned down
Has to be tested by NSF to have it qualify and be reliable
6
Which is not part of the steps of the scientific method?
Make mistakes public for rejection of research
Make an observation
Propose hypothesis
Make and test prediction
7
Which of these are important to obtain a proper measurement and correctly identifies what it measures
light sensor- measures how harmful light is
water bath-controls temperature
Measuring cylinder- measures amount of particles in a substance
stop watch- how fast something moves
8
What is an anomalous result?
The result which is removed from data because there is an exorbitant amount
Result which is predicted by scientist or researcher
A result which doesnt fit in with pattern of other results
A result which is contrained to depict similar results of others
9
Which of these methods are part of the statistical analysis?
sample names and info
hypothesis testing
standard mediation
regression
10
Which of the following is not an important example to consider when deciding on control variables?
carbon dioxide concentration
light intensity
light wavelight
name of person measuring
11
How do you calculate rate of change?
change/time
time/ amount of change that occured
seconds/hours
Change/amount of space taken up
12
what does pH measure
measures co2 and h20 in substance
How acidic something is based on its appearance
measures amount of h+ and OH ions
how something tastes based on its ions
13
What is a rule of significant figures?
Only use same number of digits as the least precise part of calculation
Only use whole number
Only use numbers after decimal, not whole number
Use all the numbers given even 10 after decimal
14
Ways an experiment can be improved
explain confounding variables
Using same methods and changing nothing
Stop controlling all variables
Finalize results with no repeat
15
Which of these are not criteria for line of best fit
Try to make line equal distance from relative points
Follow data trend
shorten line(make sure it doesnt touch axes)
Even # of plots on each side of line
16
Which of the following is a dependent variable?

17
What is scientific theory?
A possible explanation of your observation that can be tested
An explanation of the natural world supported by lots of facts and evidence
A statement of the expected results based on the hypothesis being tested
A statement or fact that tells us what will happen in future
18
What do you need to develop a hypothesis
Shouldnt be testable
Researcging problem and finding out what others have learned
Shouldnt answer original question but rather future questions
State that it is proven and not supported
19
Which pair goes together when controlling variables
pH and Buffer
Temp and WaterBomb
Light and air pump
Oxygen and hydrogen carbonate
20
which of these statements are not true about precisions and accuracy
Accuracy and precision refer to the quality of measurement
Precision is degree which an instrument/process will repeat the same value
Accuracy is how close a measurement is to the true value
Precision is how far measurement are to each other
21
Define theory
Never was a hypothesis, but statement.
IS NOT SUPPORTED BY COMMUNITY OR SCIENTISTS
Synonym of hypothesis
A hypothesis which exhaustively supproted by experimental data
22
Define an independent variable
Variables not being tested but kept in case they affect the experiment
The variable being manipulated in the experiment
A condition in an experiment that can be controlled or changed
The variable being measure in an experiment
23
what shouldnt be considered when creating graph
title
key
roman numerals
scale
24
What should you not consider when creating a conclusion?
Support whether data matches hypothesis
Evaluate hypothesis based on data and suggest improvements

quantitative data
27
How can data results NOT be reliable
Identify an anomale
Only use one type of data continuously like either quan/qual.(NEVER BOTH)
Create data that scientists cannot get hands on & repeat method/experiment
Make reliable by repeating
28
what is a reason why errors occur?
Because scientists do not have/lack problem-solving skills
