D) Hypothetical variables
E) None of these

Question 5

The method to be used in preparing samples in a research project needs to be stated precisely at all steps so that other researchers can replicate preparation of samples.

Question 6

Follow the style guide for the journal in which the paper might be published.

Question 7

Qualified researchers and scientists are the only people reporting research about food on the Internet.

Question 8

A statement of an expected positive result of an experiment is called the:

A) Dependent variable
B) Independent variable
C) Extraneous variable
D) Hypothetical variable
E) None of these.

Question 10

Development of a statement of the purpose of a research project may begin with identifying a general topic, but needs to be defined specifically so that an appropriate research design can be planned.

Question 11

Positive assumption to test logical or empirical consequences of applying a variable in a research project is called:

A) Variable
B) Extraneous variable
C) Hypothesis
D) Theory
E) None of the above

Question 12

. The calculated average of scores can be reported as the mean of the scores.

Question 13

Samples should be coded to eliminate bias from the judges.

Question 14

Control is critical in a food science experiment to eliminate the;

C) Basic concept
D) Random plan
E) Geographic atlas

Question 19

Mean and mode are synonyms that can be used interchangeably to report
experimental results.

Question 20

Plans for sensory and objective measurements and the scorecard need to be made when the experiment is planned.

Question 21

Design scorecards for sensory evaluation.

Question 22

Explain how to select and train sensory panelists.

Question 23

Decide the appropriate sensory testing to incorporate in a research study.

Question 24

Identify the characteristics of food that can be evaluated by using human senses.

Question 25

Statistical analyses are conducted to determine the probability that the observed results are due to the variable applied and not simply to chance.

Question 26

Distinguish between:

Question 27

In the above experiment, give the independent variable: [type of flour]

Question 28

In the above experiment, list five control measures that would prevent extraneous variables from affecting the experiment results:

Question 29

A student is conducting an experiment using all-purpose flour, whole wheat flour, and bread flour in a standard yeast bread recipe. Write a simple purpose statement that would be applicable to that experiment. Then write a hypothesis and null hypothesis for the same experiment.

Question 30

Describe the sensory organs and their actions.
