AP Stats 1 Flashcards
AP stats 1
objects described by a set of data
Individuals
AP stats 1
a quantity that can assume any of a set of values
Variable
AP stats 1
(statistics) an arrangement of values of a variable showing their observed or theoretical frequency of occurrence
Distribution
AP stats 1
a characteristic that can be measured numerically
Quantitative Variable
AP stats 1
a characteristic that is defined by its presence or absence in a category
Qualitative Variable
AP stats 1
places an individual into one of several groups or categories
Categorical Variable
AP stats 1
a circular chart divided into triangular areas proportional to the percentages of the whole
Pie Chart
AP stats 1
a graph with points plotted to show a possible relationship between two sets of data.
Scatter plot
AP stats 1
a bar chart representing a frequency distribution
Histogram
AP stats 1
a chart with bars whose lengths are proportional to quantities
Bar Graph
AP stats 1
a graphical device that summarizes data by the number of dots above each data value on the horizontal axis
Dot Plot
AP stats 1
displays the 5-number summary as a central box with whiskers that extend to the non-outlying data values
Boxplot
AP stats 1
A system used to condense a set of data where the greatest place value of the data forms the stem and the next greatest place value forms the leaves.
Stem & Leaf Plot
AP stats 1
a line graph of a cumulative frequency or cumulative relative frequency distribution.
Ogive
AP stats 1
plots each observation against the time at which it was measured
Time Plot
AP stats 1
having similarity in size, shape, and relative position of corresponding parts
Symmetrical
AP stats 1
The left side of the histogram extends much farther out than the right side
Skewed Left
AP stats 1
The right side of the histogram extends much farther out than the left side
Skewed Right
AP stats 1
an average of n numbers computed by adding some function of the numbers and dividing by some function of n
Mean
AP stats 1
The middle number in a set of numbers that are listed in order
Median
AP stats 1
the second moment around the mean
Variance
AP stats 1
the square root of the variance
Standard Deviation
AP stats 1
the difference between the highest and lowest scores in a distribution
Range
AP stats 1
Interquartile Range = Q3 minus Q1
IQR
AP stats 1
an extreme deviation from the mean
Outlier
AP stats 1
includes the minimum, first quartile, median, third quartile, & the maximum
5-Number Summary
AP stats 1
(statistics) any of three points that divide an ordered distribution into four parts each containing one quarter of the scores
Quartile
AP stats 1
the greatest possible degree, the point on a curve where the tangent changes from positive on the left to negative on the right
Maximum
AP stats 1
the point on a curve where the tangent changes from negative on the left to positive on the right
Minimum
AP stats 1
(statistics) any of nine points that divided a distribution of ranked scores into equal intervals where each interval contains one-tenth of the scores
Decile
AP stats 1
values that are not strongly affected by extreme values, the median is more resistant that the mean. The standard deviation is most strongly affected by extreme values
Resistant
AP stats 1
Summary measures that are greatly changed by one or more outliers
Nonresistant
