What is a bar graph?
What is necessary to determine cause and effect?
What is random assignment?
This abbreviation is used for describing correlation between 2 variables
What is DUFS?
The probability of a single event is always between these two values.
What are 0 and 1?
At confidence level a = .05, a data scientist calculates a p-value of 0.03, therefore the scientist should…
What is (reject the null/accept the alternative) hypothesis?
You can find the 5 number summary on this graph, as well as outliers.
What is a box plot?
Amanda generates a random number. She begins with that number and chooses every 5th subject from that starting point. Amanda is using this kind of sampling.
What is a systematic random sample?
This abbreviation is used to describe a distribution.
What is SOCV?
Two events A and B are called this when the probability of one event occurring does not change the probability of another.
What are independent events?
What check test is used to ensure independence between trials?
What is Large Counts?
This graph has qualitative variables on the x-axis, displaying ranges of numbers and displaying frequency on the y-axis.
What is a histogram?
A scientist is testing how WiFi affects the health of plants. In this scenario, the plants are this variable.
What are experimental units?
The abbreviations used for binomial and geometric probability
What is BINS and BITS?
The following symbol means… (A|B)
What is the probability of A given B?
The general formula for inference interval.
Point estimate +/- z-score (SE)
This graph displays the difference between the expected and actual value for many different values of x.
What is a residual plot?
Thirty people are randomly divided into 6 groups. Two groups are randomly selected, and all members in the groups selected are used within the experiment. The scientist used THIS sampling method.
What is a cluster sample?
This abbreviation is used for the linear regression CHECK for inference
What is LINER?
This principle states that as the number of trials increases, the relative frequency of an event approaches its theoretical probability.
What is the Law of Large Numbers?
To determine association between two distributions, this test is used.
What is a x2 test for independence?
This formula is used to find the expected value in a table given for chi square tests (homogeneity and independence).
What is row total x column total / total?
A LSRL has a r2 value of 0.98 and the experiment used random sampling, but not random assignment. What can be concluded as the relation between the two variables?
What is correlation?
What are the 3 conditions for inference procedure for means?
What is random sample, 10%, and Large Sample (CLT)?
You roll two fair six sided dice. This is the probability that the sum is at least 10 given that the first die shows a 6.
What is 2/3?
