Graduate Science Students. According to Survey of Graduate Science Engineering Students and Postdoctorates, published by the U.S. National Science Foundation, the distribution of graduate science students in doctorate-granting institutions is as follows. Frequencies are in thousands. Note: Earth sciences include atmospheric and ocean sciences as well. Field Frequency Agricultural sciences 15.1 Biological sciences 69.7 Computer sciences 46.1 Earth sciences 14.9 Mathematical sciences 22.0 Physical sciences 38.7 Psychology 45.6 Social sciences 97.2 A graduate science student who is attending a doctorate-granting institution is selected at random. Determine the probability that the field of the student obtained is a. psychology.b. physical or social science.c. not computer science.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
