Answers 100% Guaranteed Success.
Frequencies - correct answer.Just the count or number of observations in each
category. Abbreviated as 'n' or 'f'
Relative Frequency - correct answer.The number of times a particular observation
occurs divided by the total number of observations.
Frequency Distribution - correct answer.A summary of the numerical counts of the
values or categories of a measurement.
Cumulative Frequency - correct answer.The number of observations with a value less
than the maximum value of the variable interval.
Cumulative Relative Frequency - correct answer.A number calculated by adding
together all the relative frequencies less than or equal to the selected upper limit point.
Central Tendency - correct answer.An indicator at the center of the data.
Mean - correct answer.The arithmetic average of the observations
Median - correct answer.The center or middle of the observations when observations
are placed in order from smallest to largest
Mode - correct answer.The most commonly occurring number in the data
Measures of spread - correct answer.The spread or dispersion of observations around
the mean
Statistical Range - correct answer.The difference between the maximum and minimum
values in a distribution. Reported as a single number
, Epidemiological Range - correct answer.The smallest and largest values of the
observations. Reported as two numbers
Percentiles - correct answer.The percentage of observations that fall below a certain
value
Quartiles - correct answer.The values for which 25% (Q1), 50% (Q2), and 75% (Q3) of
the observations fall below.
Interquartile range - correct answer.The difference between the first (Q1) and third (Q3)
quartiles
Standard Deviation - correct answer.The average distance that values in a distribution
are from the center.
Z-Scores - correct answer.A measure that indicates how many standard deviations a
value is from the mean value.
Normal Distribution - correct answer.A probability distribution in which the mean,
median, and mode are equal with a bell-shaped distribution curve
Outliers - correct answer.An extreme value of a variable, one that is outside the
expected range. Defined as a value that is more than 1.5x the interquartile range above
or below the edges of the box.
Shapiro Wilkes Test - correct answer.A test for presence/absence of normality to
determine what type of statistics can be used. If the p-value is > or = to .05, there is
NOT a statistically significantly difference in distribution = a NORMAL DISTRIBUTION.
If p-value is < .05, there is a statistically significant difference between the distribution of
the variable. NOT NORMAL DISTRIBUTION
How nominal data can be summarized using descriptive statistics - correct answer.Only
mode can only be used for nominal variables
How ordinal data can be summarized using descriptive statistics - correct answer.Data
that is rank ordered can be described using the median
How interval/ratio data can be summarized using descriptive statistics - correct
answer.Data that is continuous can be described using the mode, median, or mean.
Best graphical display of nominal data - correct answer.Bar charts. Only shows a
difference and is not rank ordered.
How to determine normality using histograms - correct answer.Mean, median, and
mode are the same. When cut in half, one side mirrors the other
