frequency
Frequency is the number of occurrences of a repeating event per unit time

average
In colloquial language, an average is the sum of a list of numbers divided by the number of numbers in the list

normal distribution
In probability theory, the normal distribution is a very common continuous probability distribution
Got it
expected value
In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents
Got it
statistical significance
In statistical hypothesis testing, statistical significance is attained whenever the observed p-value of a test statistic is less than the significance level defined for the study

bar graph
A bar chart or bar graph is a chart that presents grouped data with rectangular bars with lengths proportional to the values that they represent
contingency table
In statistics, a contingency table is a type of table in a matrix format that displays the frequency distribution of the variables
scatter plot
A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data
percentile
A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall
cumulative frequency
Cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value
pie chart
A pie chart is a circular statistical graphic, which is divided into slices to illustrate numerical proportion
Independent events
In probability theory, two events are independent, statistically independent, or stochastically independent if the occurrence of one does not affect the probability of the other
