Question 1

usually written using capital
letters, is a variable that assigns a numerical value to each outcome of a random event. It can be classified as discrete or
continuous.

Answer 1

random variable

Question 2

is a variable whose value is obtained through counting. It takes on countable numbers of distinct
values which are whole numbers

Answer 2

discrete variable

Question 3

variable whose value is obtained through measurement. It assumes an infinite number of possible values including the decimals between two counting numbers

Answer 3

continuous variable

Question 4

is the set of all possible outcomes in an
experiment.

Answer 4

sample space

Question 4

are values that are obtained from functions that assign real number to each
point of a sample space

Answer 4

possible values of a random variable

Question 5

properties of discrete probability distribution/probability mass function

Answer 5

1. probability of each value must be between or equal to 0 and 1
2. the sum of all the values of the random variable is equal to 1

Question 6

is a probability distribution with only two possible outcomes: success and failure

Answer 6

binomial distribution

Question 7

is the average value of all
the outcomes

Answer 7

mean

Question 8

describes the average
square deviation of the variable from the mean

Answer 8

standard deviation

Question 9

a measure of the spread of the data set equal to the
mean of the square variations of each data value from the mean
of the data set

Answer 9

variance

Question 10

is a part of the sampling technique in which
each sample has an equal probability of being chosen

Answer 10

random sampling

Question 11

is a frequency distribution
using the means computed from all possible random samples of a
specific size taken from a population

Answer 11

sampling distribution of sample means

Question 12

The difference between the sample mean and the population mean

Answer 12

sampling error
