Central Tendency
100
It is known as the science of collecting, organizing, summarizing, analyzing and making inferences from data.
What is Statistics
100
It occurs when every member of the population has an equal chance of being selected.
What is Random Sampling
100
It is a generalized rule for the union of two events.
What is Addition Rule
100
It gives some general statements relating the mean and the standard deviation of a bell shaped distribution.
What is Empirical Rule
100
It also referred to as average.
What is Mean
200
It is variable that can assume all values between any two given values.
What is Continuous Variable
200
It occurs when the population is subdivided by similar characteristics and a sample is taken from the sub-populations.
What is Stratified Sampling
200
Two events that cannot occur at the same time are described as
What is Mutually Exclusive
200
True or False The interquartile range is the difference between the lower boundary and the median?
What is False
200
It is the most populous value in a data set.
What is Mode
300
It is a level of measurement characterized by data that consists of names, labels and categories only.
What is Nominal
300
It occurs when every ‘nth member of a population is selected.
What is Systematic Sampling
300
It is the collection of all possible results of an experiment.
What is Sample Space
300
True or False The standard deviation is the square of the variance?
What is False
300
It is determined by first sorting the data set from lowest to highest then finding the data point in the middle.
What is Median
400
What is parameter?
What is A numerical measurement that describes something about a population.
400
It occurs when the population is divided into sections and a few of those divisions are chosen and all the members of that section make up the sample.
What is Cluster Sampling
400
If P(A)=0.5, P(B)=0.6, and P(A∩B)=0.7, then P(A∪B)=
What is 0.4
400
For a set of numerical values, it is the difference between the largest and smallest value in the data set?
What is Range
400
When Q2 is closer to Q1 than it is to Q3, the data set is described as
What is Positively Skewed
500
A type of collected information such as: colors, textures, appearance, and smells.
What is Qualitative Data
500
It occurs when the results of an experiment are used because they are readily available.
What is Convenience Sampling
500
The probability of an NBA team making the playoffs.
What is 16/30 or 8/15
500
You find it by dividing the Standard Deviation by the mean and then multiplying by 100.
What is Coefficient of Variation
500
This is created when straight lines connect the frequency of each class, which is indicated by points or dots drawn at the midpoints of each class interval.
What is Frequency Polygon
