(a) Statistics are used to eliminate uncertainty
(b) Statistics are used to measure uncertainty
(c) Statistics are used to increase uncertainty
(d) Statistics do not relate to uncertainty
(a) Experimentation, comparison, and modeling
(b) Mean, median, and standard deviation
(c) Ammonia, cyanamide, and urea
(d) Controls, randomization, and replication
(a) The assignment of controls or treatments in a manner to minimize confounding variables
(b) The assignment of controls or treatments completely at random
(c) The random sampling of research data across different types of experiments
(d) The random assignment of researchers to projects to assure no personal bias in scientific research
(a) are used to sum up major attributes of a dataset.
(b) are used to model patterns in data or make judgments about data.
(a) it is a very important conclusion.
(b) the conclusion is definately correct.
(c) there is a high probability that the conclusion is due to a random association.
(d) there is a low probability that the conclusion is due to a random association.
Statistics may be defined as a body of methods for making wise decisions in the face of uncertainty.
