The independent variable

is what the investigator changes in an experiment

Which sentence represents a hypothesis?

Environmental conditions affect the pollination of plants.

Which activity would be an appropriate first step when designing an experiment?

research problem, using information from different sources

Which statement about the use of independent variables in controlled experiments is correct?

Only one independent variable is used for each experiment

The analysis of data gathered during a particular experiment is necessary in order to

draw a valid conclusion for that experiment

Which statement best describes a hypothesis

A hypothesis is as a basis for deciding what data to collect

The dependent variable

is the data collected in an experiment

Conclusions based on an experiment are most likely to be accepted when

they are consistent with experimental data and observations

thermometer
5
Which activity would be an appropriate first step when designing an experiment?
repeating the experiment with a different hypothesis
creating a data table to organize experimental observations
reporting a conclusion based on multiple experimental trials
research problem, using information from different sources
6
Which statement about the use of independent variables in controlled experiments is correct?
The independent variables must involve time.
Only one independent variable is used for each experiment
A new ind. variable must be used when experiment is repeated
The independent variables state the problem being tested
7
The dependent variable is put on the
x axis of the graph
y axis of the graph
8
The analysis of data gathered during a particular experiment is necessary in order to
draw a valid conclusion for that experiment
develop a research plan for that experiment
formulate a hypothesis for that experiment
design a control for that experiment
9
Which statement best describes a hypothesis
A hypothesis is as a basis for deciding what data to collect
Facts collected from an experiment r written as a hypothesis
The conclusion from results of experiment is the hypothesis
A hypothesis is the process of making careful observations
10
The dependent variable
is the data collected in an experiment
is what the investigator changes in an experiment
is controlled in the experiment
is never changed in the experiment
11
Controlled variables are
changed in the experimental group
kept the same in all groups
changed in the control group
kept the same in only two experimental groups
12
Conclusions based on an experiment are most likely to be accepted when
derived from investigations having many experiment variables
scientists agree that only one hypothesis has been tested
they are consistent with experimental data and observations
hypotheses are based on one experimental design
