1.
A value that represents the middle of a data set, often measured using the mean, median, or mode.
2.
The way a data set is distributed when graphed, such as symmetrical, skewed left, or skewed right.
3.
A measure of how far apart the values in a data set are, often described using range or interquartile range (IQR).
4.
A conclusion or prediction made based on data and statistical analysis.
5.
Sample: A subset of a population where each member has an equal chance of being chosen, helping to make fair and unbiased conclusions.
6.
Graph: A graph in the shape of a circle, also called a pie chart, that shows how parts compare to a whole.
7.
The entire group being studied in a survey or experiment.
8.
Plot: A graph that shows the distribution of data using a box and whiskers, highlighting the median and quartiles.
9.
A guess or estimate based on patterns or data trends.
10.
Box Plot: Two box plots displayed together, used to compare two sets of data.
11.
Dot Plot: Two dot plots shown together to compare two sets of data points.
12.
The study of collecting, organizing, analyzing, and interpreting numerical data.
13.
A method of collecting data by asking people questions.
14.
Range: (IQR) The difference between the third quartile (Q3) and the first quartile (Q1) in a data set, showing the spread of the middle 50% of values.
15.
– The number(s) that appear most frequently in a data set.
16.
The difference between the highest and lowest values in a data set.
17.
A distribution where data is not evenly spread around the center; it may be skewed left or right.
18.
– The average of a data set, found by adding all numbers and dividing by the total count of numbers.
19.
The middle number in an ordered data set; if there is an even number of values, the median is the average of the two middle numbers.
20.
– A data set where the left and right sides are mirror images of each other when graphed.
21.
A ratio that compares one part of a group to the entire group.
22.
A ratio that compares one part of a group to another part within the same group.
23.
Left – A data distribution where most values are on the higher end, with a longer tail on the left.
24.
Right: A data distribution where most values are on the lower end, with a longer tail on the right.
