ACTUAL QUESTIONS WITH VERIFIED
ANSWERS.
Measures of central tendency - correct answer-This provides
descriptions of the middle values of a data set. Includes mean,
median and mode.
Mean - correct answer-The average of a set of numbers
Mean formula - correct answer-"The sum of observations / n"
where n is equal to the number of observations.
Find the mean of these numbers: 5, 8, 17, 20, 0 - correct
answer-10 (5+8+17+20+0)/5=10
Median - correct answer-the middle score in a distribution; half
the scores are above it and half are below it. Depending on an
odd or even number of observations it is calculated differently.
REMEMBER!!! The median is NOT a calculation of the middle.
,You cannot just take the low and high and find the middle. The
median must be either the central outcome that occured (odd
number in set) or the average of the two central outcomes that
occured (even number in set).
Find the Median from this set: 1, 9, 10. - correct answer-The
median is 9. Remember that median does not really mean
"middle" in terms the the range. It just means middle number/s
in the set.
Find the Median: 1, 2, 4, 10 - correct answer-The Median is
three. (2+4)/2=3. When there are even numbers of
observances you must take the average of the two numbers
that fall in the middle.
Mode - correct answer-the most frequently occurring score(s) in
a distribution
Find the mode: 44,29,13,44,15 - correct answer-44. You WILL
get a question this easy on the test. Don't blow it!!!
, Frequency distribution - correct answer-an arrangement of data
that indicates how often a particular score or observation
occurs
Histogram - correct answer-A graph of vertical bars
representing the frequency distribution of a set of data.
Histogram vs bar chart - correct answer-A histogram represents
the frequency distribution of continuous variables. Conversely,
a bar graph is a diagrammatic comparison of discrete variables.
Histogram presents numerical data whereas bar graph shows
categorical data. The histogram is drawn in such a way that
there is no gap between the bars.
Histogram vs bar chart in simple terms - correct answer-A bar
chart measures different non numerical categories. Like
frequency of hair styles chosen some tuesday at a hair salon. A
histogram would measure a numerical value on both the x and
y. Like how many haircuts where given each month for a year
the the said salon. The bars on the histogram are always
touching each other so that reading trends is easier.
