Understanding Cumulative Frequency and Stem-and-Leaf Plots

These flashcards cover key vocabulary related to cumulative frequency and stem-and-leaf plots, as discussed in the lecture.

Cumulative Frequency

A running total of frequencies that helps in understanding frequency distribution.

Frequency Table

A table that displays the frequency of various outcomes in a sample.

Histogram

A graphical representation of the distribution of numerical data, often used with frequency tables.

Stem and Leaf Plot

A method for displaying quantitative data that retains the original data values while displaying the distribution.

Samples in Statistics

A subset of individuals from a population used to estimate characteristics of the entire population.

Arithmetic vs. Sampling

Arithmetic involves calculations on known values, while sampling refers to selecting a subset from a larger population for analysis.

Vertical Stem and Leaf Plot

A variation of a stem and leaf plot where the stem is presented at the bottom and leaves are shown above it.

Arranging Data

The process of organizing numbers in order, usually ascending, prior to creating graphs like stem and leaf plots.

Repeating Values

In stem and leaf plots, when the same number appears multiple times, each instance must be recorded.

Exam Techniques

The ability to quickly apply learned concepts, like creating stem and leaf plots, during assessments.
