Review on Research I

The first question of the “Four Question strategy” lets you identify _______ of the experiment.

• the procedure

• the materials

• the hypothesis

• the title

An interpolated prediction is more accurate than an extrapolated prediction because_____.

• it lies between two known data

• it lies beyond a known data

• it is based on actual measurements

• it is supported by the hypothesis

For which of the following sets of data is a line graph most appropriate?

• The height of a tree in the park on January 1 for the past 15 years

• The percentage of students in your class with brown eyes

• The highest yearly temperatures in four cities in the Philippines

• The comparison between twin brothers’ changes in heights (in cm) for a period of

  18 years  

The number of constants to be listed depends on ______ of the Four-Question Strategy.

• how many factors are listed in Question 3

• the availability of materials listed in Question 1

• how many factors are listed in Question 4

• the remaining factors in Question 3 (not chosen as IV)

Which of the values for distance of spring stretch is the possible extrapolated prediction for the data in the table?

• 16 cm

• 14 cm

• 10 cm

• 8.5 cm

In “Question 3” of the 4-Question strategy, all potential manipulated variables must be listed. When only one is considered as the independent variable, all others are considered the _____.

• dependent variables

• control setups

• constants

• experimental variables

Which of the following sources of errors will have the LEAST effect on the results of an experiment?

• No repeated trials

• Not having a control setup

• Not keeping other factors constant (other than the IV)

• Not using quantitative measurements

Students created a data table showing the kinds of candy in a grocery store. They

wanted to make a graph, so they could show the data in a second way. What kind of

graph is most appropriate for the data?

• Line graph

• Bar graph

• Pie graph

• All of the above

In the given graph sketch of three cyclists, which statement is correct?

• Cyclist A traveled the least distance.

• Cyclist B reached the lowest speed.

• Cyclist C traveled the least distance and had the lowest speed.

• Cyclist A probably had a flat tire.

The number of constants to be listed depends on ______ of the Four-Question Strategy.

• how many factors are listed in Question 3

• the availability of materials listed in Question 1

• how many factors are listed in Question 4

• the remaining factors in Question 3 (not chosen as IV)
