ANSWERS
What are the different types of data? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Categorical (nominal and ordinal) and Scale
|\ |\ |\ |\ |\ |\
(interval and ratio)
|\ |\ |\
What is categorical data? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\
✔✔Numbers represent categories of information
|\ |\ |\ |\
What is nominal data? - CORRECT ANSWERS ✔✔Data
|\ |\ |\ |\ |\ |\ |\ |\
grouped into unordered categories (I,e, yes = 1, no = 0)
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
What is ordinal data? - CORRECT ANSWERS ✔✔Data
|\ |\ |\ |\ |\ |\ |\ |\
which is placed into order/ranked but the distances
|\ |\ |\ |\ |\ |\ |\ |\
between the scores is not known (i.e. pain scale)
|\ |\ |\ |\ |\ |\ |\ |\
What is scale data? - CORRECT ANSWERS ✔✔A numerical
|\ |\ |\ |\ |\ |\ |\ |\ |\
measurement of something, in which the difference |\ |\ |\ |\ |\ |\ |\
between values has meaning|\ |\ |\
What is interval data? - CORRECT ANSWERS ✔✔Data
|\ |\ |\ |\ |\ |\ |\ |\
measured on a scale where each point is at a equal
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
,distance from one another & there is no true zero (i.e.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
temperature in celsius) |\ |\
What is ratio data? - CORRECT ANSWERS ✔✔data
|\ |\ |\ |\ |\ |\ |\ |\
measured where numbers are not restricted to certain
|\ |\ |\ |\ |\ |\ |\ |\
values, & there is a true zero (i.e. amount of money in the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
bank)
|\
What is an absolute frequency table? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔A table used to display data where |\ |\ |\ |\ |\ |\ |\ |\
information in the right-hand column is a number of |\ |\ |\ |\ |\ |\ |\ |\ |\
observations/counts
How are absolute frequency tables used for categorical
|\ |\ |\ |\ |\ |\ |\ |\
data? - CORRECT ANSWERS ✔✔The table shows a set of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
categories in one column & the counts in the adjacent
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
column.
How are absolute frequency tables used for scale data? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔The table shows data in one
|\ |\ |\ |\ |\ |\ |\ |\
column and counts in another. It can also use intervals to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
group data & show the counts within each interval.
|\ |\ |\ |\ |\ |\ |\ |\
Absolute VS Relative Frequency Distribution - CORRECT
|\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Absolute frequency shows raw data. |\ |\ |\ |\ |\ |\
Relative frequencies are proportions/percentages.
|\ |\ |\ |\
,Relative frequency is found by dividing the number of
|\ |\ |\ |\ |\ |\ |\ |\ |\
values in an interval by the total number of values in the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
table (times 100 for %).
|\ |\ |\ |\
What is central tendency? - CORRECT ANSWERS ✔✔The
|\ |\ |\ |\ |\ |\ |\
"average", or somewhere in the middle of the data set
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
What are the 3 main measures of central tendency? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Mean, median & mode |\ |\ |\ |\ |\
Mean - CORRECT ANSWERS ✔✔The sum of all values
|\ |\ |\ |\ |\ |\ |\ |\ |\
divided by the number of values (x bar)
|\ |\ |\ |\ |\ |\ |\
Median - CORRECT ANSWERS ✔✔The middle value in a
|\ |\ |\ |\ |\ |\ |\ |\ |\
data set when arranged from lowest to highest. If the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
number of values in off, take the middle number. If the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
number of values is even, take the mean of the middle 2.
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Mode - CORRECT ANSWERS ✔✔The most common value.
|\ |\ |\ |\ |\ |\ |\ |\
In a data set, there could be no mode, 2 modes (bimodal),
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
3 modes (trimodal) or more (multimodal).
|\ |\ |\ |\ |\ |\
Which measure of central tendency is most effected by
|\ |\ |\ |\ |\ |\ |\ |\ |\
outliers? - CORRECT ANSWERS ✔✔The mean can |\ |\ |\ |\ |\ |\ |\
, drastically change, but median and mode can stay the
|\ |\ |\ |\ |\ |\ |\ |\ |\
same.
Which measure of central tendency do I use when dealing
|\ |\ |\ |\ |\ |\ |\ |\ |\
with nominal data? - CORRECT ANSWERS ✔✔Since the
|\ |\ |\ |\ |\ |\ |\ |\ |\
numbers associated with the data do not have qualitative
|\ |\ |\ |\ |\ |\ |\ |\
meaning, calculations mean nothing. Mode is the best
|\ |\ |\ |\ |\ |\ |\ |\ |\
indicator as it tells which category appears most
|\ |\ |\ |\ |\ |\ |\ |\
frequently.
Which measure of central tendency do I use when dealing
|\ |\ |\ |\ |\ |\ |\ |\ |\
with ordinal data? - CORRECT ANSWERS ✔✔In ordinal
|\ |\ |\ |\ |\ |\ |\ |\ |\
data, the numbers represent categories which are
|\ |\ |\ |\ |\ |\ |\
ordered. The mode makes the most sense when dealing
|\ |\ |\ |\ |\ |\ |\ |\ |\
with ranks (i.e. saying you ranked 3/5 rather than 3.216)
|\ |\ |\ |\ |\ |\ |\ |\ |\
Which measure of central tendency do I use when dealing
|\ |\ |\ |\ |\ |\ |\ |\ |\
with scale data? - CORRECT ANSWERS ✔✔Numbers are
|\ |\ |\ |\ |\ |\ |\ |\ |\
true values, thus the mean or median can be used.
|\ |\ |\ |\ |\ |\ |\ |\ |\
Are variability of data and spread of data
|\ |\ |\ |\ |\ |\ |\ |\
interchangeable? - CORRECT ANSWERS ✔✔Yes |\ |\ |\ |\
How does range describe variability of data? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Range measures the spread of data by
|\ |\ |\ |\ |\ |\ |\ |\
