Exam 2025 With 100% Correct Answers
distribution - correct answers ✔✔an arrangement of values that demonstrates their frequency
or occurrence
pie chart - correct answers ✔✔categorical data, %
bar chart - correct answers ✔✔categorical data; displays counts or frequencies for a category
dot plot - correct answers ✔✔quantitative data, data is represented by a single point
stem plots - correct answers ✔✔quantitative data, shows distribution while representing
specific data points
box plots - correct answers ✔✔quantitative data, can be used to compare data sets, each part is
25% of data
histograms - correct answers ✔✔quantitative data, display frequencies or counts
quantitative data - correct answers ✔✔numerical data, it makes sense for it to be added
categorical data - correct answers ✔✔data that consists of names, labels, or other
nonnumerical values
, relative frequency - correct answers ✔✔a way to approximate a percentage by dividing the
number of times an event occurred by the number of trials
frequency distribution - correct answers ✔✔a record of the number of times data occurs within
a certain category
outliers - correct answers ✔✔an observation point (number) that is distant from the other
observations of a data set
center - correct answers ✔✔a measure of central tendency that is used to describe an entire set
of data with one value that represents the middle or center of the distribution (mean, median,
mode)
interval - correct answers ✔✔a set of numbers between two specified values
check sheet - correct answers ✔✔a table that allows data to be collected by marking how often
an event has occurred in a certain interval
symmetric distributions - correct answers ✔✔the left half of a data set being roughly identical
to the right half
bell curve - correct answers ✔✔normal distribution, results from graphing frequency versus
distribution for a trait that varies continuously in a population
skewed-right - correct answers ✔✔type of data distribution where frequency starts small,
increases, then gradually decreases again
skewed-left - correct answers ✔✔distribution where data starts small and consistently increases
before dropping off again
