Histogram
this graph x-axis represents containers similar to ranges of information; its y-axis shows the
frequency of observations falling into every bin.
Outlier
value that falls far from the relaxation of the statistics.- We must usually carefully inspect an
outlier before finding out whether or not to leave it as is, alternate its cost
to the perfect price, or take away it.

scatter plot
graphing variables like this will screen relationships among variables ( information units).
- Although there may be a courting between two variables, we can not finish that one variable
"causes" the alternative. This factor is quality summarized in the admonition, "correlation does
no longer suggest causation."
hidden variables
which may be responsible for patterns we see while graphing or examining relationships
between two facts units.
Descriptive data
aka also called precis data
imply, median
, mode
suggest, median, mode
three values describe the middle or central tendency of the records set
imply
is same to sum of all statistics points inside the set divided by using the wide variety of data
factors
median
the center price of the records set: half of of the information set's values lie beneath the median,
and half lie above the median.
Mode
the fee that happens maximum often within the information set. A information set may also have
more than one modes.
Variety, variance, widespread deviation
measure the spread of the facts
trendy deviation
square root of the variance
coefficient of variant
used to evaluate version in special information units
measures the scale of the standard deviation relative to the dimensions of the imply (that is,
coefficient of variation= )
conditional mean
the imply of a subset of the information that includes all values pleasing a certain situation.
Percentile
may be some other cost of interest. For example, 60% of the observations are less than or
equal to the 60th percentile. The median is by means of definition the fiftieth percentile of a
information set.
