Graphs
stem plot definition
a data visualization tool that displays the distribution of a dataset by separating each data point into a "stem" (the leading digits) and a "leaf" (the final digit)
Statistics
the practice or science of collecting and analyzing numerical data in large quantities
Center
In statistics, the "center" of a dataset refers to a central value that summarizes the data
Bar graph
A bar graph is a statistical visualization tool that uses rectangular bars to represent and compare numerical data across different categories.
Split stems definition
"Split stems" can refer to two different concepts: in statistics, it's a method of creating a split-stem plot to provide a more detailed view of data distribution by splitting each stem into two parts.
an individual is a single member of a group being studied, which can be a person, animal, plant, or object.
Spread
Spread is a measure of how spread out the values in a dataset are
Pie chart
A pie chart is a circular graph where each slice represents a proportion or percentage of a whole dataset
Dot plot definition
A dot plot is a simple statistical chart that uses dots to represent data points on a number line, making it easy to visualize the distribution, frequency, and spread of a dataset
Variables
In statistics, a variable is any characteristic, number, or quantity that can be measured or counted.
Skewed
Skewed refers to an asymmetrical or uneven distribution of data, where the data is not a mirror image of itself on either side of the mean
Segmented bar graph
A segmented bar graph is a type of bar graph that displays data for two categorical variables, where each bar is divided into segments to represent a sub-category
Histogram definition
A histogram is a graphical representation of the distribution of a set of continuous data, displayed as a series of adjacent bars where the area of each bar is proportional to the frequency of values within that range
Quantative
Quantitative definition statistics refers to the branch of statistics that uses and analyzes numerical data to identify patterns, make comparisons, and answer questions like "how many," "how much," or "how often"
Outliar
An outlier is a data point that differs significantly from other observations in a dataset, representing an extreme value that is either much higher or much lower than the rest
A two-way table is a statistical tool used to display and analyze the relationship between two categorical variables
Box plot definition
A box plot is a graphical tool that summarizes a dataset using its five-number summary: minimum, first quartile (Q1), median (Q2), third quartile (Q3), and maximum
Shape
In statistics, "shape" describes the overall form or pattern of a data distribution as shown in a graph like a histogram, indicating characteristics such as symmetry, skewness, and modality
What is conditional distribution?
A conditional distribution is the probability distribution of a random variable given that another random variable has a specific, known value
What is a frequency table?
A frequency table is a way to organize and display data by showing the number of times each value appears in a dataset
