ATI TEAS 7 MATHS QUESTIONS AND
ANSWERS
finding the percentage - ANSWER >>>% = p (part)/ w (whole)
finding the part - ANSWER >>>p (part) = w (whole) x %
finding the whole - ANSWER >>>w (whole) = p (part) / %
percent increase - ANSWER >>>percent increase = new amount -
original amount / original amount x 100
mean - ANSWER >>>found by adding all numbers in a set together
and dividing that by the number of the numbers in a set
median - ANSWER >>>arrange numbers from least to greatest and
then find the middle number; when there are an even amount of
numbers in a set, find the average (mean) of those two numbers
mode - ANSWER >>>arrange numbers from least to greatest, then
find the number (s) that occurs the most often
, range - ANSWER >>>subtract the smallest number from the highest
number in a set
standard deviation - ANSWER >>>a measure of variability that
describes the average distance of every score from the mean
low standard deviation - ANSWER >>>data is tightly clustered around
the mean
high standard deviation - ANSWER >>>data is loosely spread over a
range of values
symmetry - ANSWER >>>data is equally distributed on either side of a
line or point
number of peaks - ANSWER >>>when data has multiple local maxima
or minima; data can be bimodal (two peaks), unimodal (one peak), or
multimodal (more and two peaks)
skewness - ANSWER >>>when data is not equally distributed on
either side of a line or point
uniform data - ANSWER >>>When the frequency of each value of a
variable in a graph is evenly spread out across the values of all
variables.
types of trends - ANSWER >>>linear, exponential, and quadratic
direction of trends - ANSWER >>>positive (increasing), negative
(negative), no change (flat)
rate of change - ANSWER >>>describes how a quantity is changing
over time
linear trend - ANSWER >>>a straight line (line of best fit) can be
drawn through the data
