___of the observations are within 2 standard deviations (±2σ) of the mean.
frequency polygon.
discrete.
a summary measure that describes a characteristic of an entire population..
The normal probability distribution is bell-shaped and symmetric..
class boundries.
sample.
a sequence of raw data in rank order from the smallest to the largest observation..
yield values that represent quantities (weight, salary, return-on-investment, GPA, # of children)..
statistic.
a graphical representation of data where slices of the pie, represented by degrees, are associated with the frequency or proportion of observations falling into a category..
The curve is asymptotic, meaning that it approaches the horizontal axis at both ends.
a tabular summary of a set of data that accumulates information from class to class. This type of tabular summary can be constructed from frequency and relative frequency distribut.
If the shape of the distribution/histogram is bell- shaped, we can make the following statements.
These numeric indices describe three major properties of numeric data.
chart where vertical bars are plotted in descending order, combined with a cumulative percentage line.
graphical representation of data where each category is depicted by a bar representing the frequency or proportion of observations falling into a category..
a measure of relative location that describes how far an individual observation is from the mean.
the manner in which data are distributed .
It provides the theoretical framework for statistical inference through .
a tabular summary of a set of data showing the proportion of observations in each of the defined categories..
There is an entire family of normal distributions, defined by the mean and variance.
those methods involved in the collection, summarizing (numerically or graphically), presenting, and analyzing a set of data in order to describe the various features of that data s.
The measures of center, (mean, median, mode), are identical and occur at the point where the normal curve is highest.

The most important type of continuous random variable is characterized by a .
These numeric indices describe three major properties of numeric data:.
continuous.
separates data into stems (leading digits) and leaves (or trailing digits)..
68.26% of values are within 1 standard deviation of the mean. 95.44% of values are within 2 standard deviations of the mean. 99.73% of values are within 3 standard deviations of th.
Standard deviation .
gives us the graph of the histogram that represents the continuous random variable. .
measure of variability that utilizes all data values. A measure that reflects how, on the average, observations vary or deviate from the mean..
right skewed.
Many continuous random variables are naturally described by a .
– a distribution in which one half of the data are a mirror image of the other half.
The total area under the curve is equal to one..
a tabular summary of a data showing the frequency (or percent) of items in each of several distinct categories..
population.
_____of the observations are within 3 standard deviations (±2σ) of the mean.
Approximately ____% of the observations are within 1 standard deviation (±1σ) of the mean.
those methods that use data from a smaller group (sample) to make conclusions/decisions about the characteristic of a larger group (population)..
The random variable X has an infinite range..
variable.
left skewed.
data.
The standard deviation determines the width of the curve. Larger values of the standard deviation result in wider, flatter curves; while smaller values result in thinner, more peak.
 .
a summary table of data showing the number of observations in each of the defined numerically-ordered categories (or classes)..
