Statistic

What is a dot plot?

• a data display that shows data as dots above a number line; may also be called a line plot

• a visual display of data set on a number line that shows the minimum, the lower quartile, the median, the upper quartile, and the maximum

• a numerical count of how many times a data value occurs in a data set

• a data display similar to a bar graph; groups the data into equal-size intervals

Median

• the middle number in an ordered set of values; if the set has an even number of values, you must find the average of the two numbers in the middle

• a data value that is much greater or much less than the other values in the data set

• a numerical count of how many times a data value occurs in a data set

• the sum of a set of values divided by the number of values; often called the average

What type of graph groups data into equal-size intervals

• dot plot

• line plot

• box plot

• histogram

The number that appears the most often is called the ___

• mean

• median

• mode

• range

The number found in the middle of the data set when it is listed in order is ____

• mean

• median

• mode

• range

What is a statistical question?

• a question that can be answered by collecting data that are expected to vary

• a question that shows data as dots above a number line; may also be called a line plot

• a question that is much greater or much less than the other values in the data set

• a question of how many times a data value occurs in a data set

The FIRST and MOST IMPORTANT step when answering questions about numerical data is to....

• Put the numbers in order from LEAST to GREATEST

• Put the numbers in order from GREATEST to LEAST

• Get rid of the even numbers

• Get rid of the odd numbers

Range

• The difference between the greatest value (maximum) and the least value (minimum)

• The sum of a set of values divided by the number of values; often called the average

• The number or numbers that occur most frequently in the data

• The difference between the upper quartile and the lower quartile

Outlier

• an interval of the number line for which a distribution has no data values

• an extreme value in a data set that is either much larger or much smaller than all the other values.

• a visual display of data set on a number line that shows the minimum, the lower quartile, the median, the upper quartile, and the maximum

• the number or numbers that occur most frequently in the data

all the values between two given values

• gap

• interval

• peak

• cluster
