AP Statistics Unit 1 Vocabulary Quiz

Match the following types of plots:

• Histogram

• The height of each bar shows

  the number or proportion of observations that

  fall within the interval corresponding to that

  bar. Altering the interval widths can change the

  appearance of the histogram.

• Dot Plot

• Represents each observation by

  a dot, with the position on the horizontal

  axis corresponding to the data value of that

  observation, with nearly identical values

  stacked on top of each other.

• Box Plot

• A graphical representation of

  the five-number summary (minimum, first

  quartile, median, third quartile, maximum).

• Stem and Leaf Plot

• Each data value is split

  into the first digit or digits and the last digit.

• Segmented Bar Plot

• Examples of bar graphs for one categorical variable, broken down by categories of another

  categorical variable.

The elements of a 5-number summary start at the beginning of the ​​range which is the ​ (a)   . The next part is the IQR​ which starts with ​ (b)   , has a bar for the ​ (c)   and ends with ​ (d)   . Finally this ends with the ​ (e)   . Outliers are marked by asterisks or other dots.

• minimum
• Q1
• median
• Q3
• maximum
• mean
• mode
• left skew
• right skew

When the majority of the data is to the right of the graph and there are outliers to the left, the graph is ​ (a)   . Therefore the mean is ​ (b)   the median.

• left-skew
• below
• right-skew
• symmetric
• equal to
• above

When the majority of the data is to the left of the graph and there are outliers to the right, the graph is ​ (a)   . Therefore the mean is ​ (b)   the median.

• right-skew
• above
• symmetric
• equal to
• left-skew
• below

When the majority of the data is distributed equally across the graph and there are no outliers, the graph is ​​ (a)   u. Therefore the mean is ​ (b)   the median.

• uniform
• equal to
• symmetric
• left-skew
• below
• right-skew
• above

Draw the outline of a normal distribution: graph, x-axis, mean required.

Based on the Empirical Rule, make the following true:

​ (a)   of data is contained in one standard deviation from the mean.

​ (b)   of data is contained in two standard deviations below the mean.

​ (c)   of data is contained in three standard deviations above the mean.

• 68%
• 47.5%
• 49.85%
• 95%
• 99.7%
• 34%

Let's try out prefixes.

Describing modes of data from least to greatest: ​ (a)   ​ (b)   ​ (c)   .

• unimodal
• bimodal
• polymodal
• univariate
• bivariate
• polynomial

Let's try out prefixes.

Describing variable data from least to greatest: ​ (a)   ​ (b)   .

• univariate
• bivariate
• unimodal
• bimodal
• polymodal
• polynomial

The pth percentile is interpreted as the value that has p% of the data less than or equal to it. Put the following in percentile order:

• Max

• 0%

• Q3

• Min

• Median
