Module 4 Question and answers 100%
correct 2025/2026
Outlier - correct answer ✔An observation point that is significantly distant from the other observations
in the dataset
Mode - correct answer ✔The most frequent value in a dataset
Statistics - correct answer ✔The science that deals with the interpretation of numerical facts or data
through theories of probability. Also, the numerical facts or data themselves.
Standard Deviation (SD) - correct answer ✔The measure on average of how far the data points are
from the mean
Mean - correct answer ✔Average, calculated by adding a series of elements in a data sat together and
dividing by the total number in a series. (Symmetric distribution)
Box plots (box-and-whisker plots) - correct answer ✔A graphical rendering of the range and the first
and third quartile of a data set with the data set's median in between. Useful in illustrating the
distribution shape of a date set.
Symmetry - correct answer ✔The quality of the data having the same shape on both sides of the mean
Interquartile Range (IQR) - correct answer ✔The difference, value, between the bottom and the top
25% of the sample or population.
Range - correct answer ✔The difference between the maximum and minimum values
, maximum - correct answer ✔The largest value in a set
Measure of central tendency - correct answer ✔A summary measure that is used to describe an entire
set of data with one value that represents the middle or center of the data set's distribution. There are
three main measures: mean, median, or mode.
normal distribution (bell curve) - correct answer ✔A common type of distribution of data points that
forms a bell shaped, symmetrical curve around the mean
Measures of spread - correct answer ✔A number of measures used to determine the distance of data
from the center of the data set, such as range and standard deviation
Skewed distribution - correct answer ✔A distribution that is not symmetrical, but has a greater
quantity of data on one side of the mean
Center - correct answer ✔One of three measures that describe what is "normal" in a data set: mean,
median, or mode.
Bimodal - correct answer ✔A description of a data set with two modes
The standard deviation rule - correct answer ✔A standard proportion or percentage of data points that
lie within each standard deviation away from the main from a normal distribution
Quantitative data - correct answer ✔Data values that are numbers, representing quantities that can be
counted or measured
Unimodal - correct answer ✔A set of data having one mode
