Mean, Median, Mode, Range
The average of numeric data.
What is the MEAN?
This is what the "Q" stands for in Q1, Q2, Q3.
What is QUARTILE?
Graph that shows the first digits of the number (thousands, hundreds or tens) as the stem and shows the last digit (ones) as the leaf.
What is a STEM AND LEAF PLOT?
Characteristics include an appearance similar to a vertical bar chart, but there are no gaps between the bars.
What is a HISTOGRAM?
Graph that consists of a box and two lines called whiskers.
What is a BOX PLOT?
The value that shows up most often.
What is the MODE?
The first step to finding IQR.
What is Order the data from least to greatest?
Characteristics include a number line with dots representing each individual data point.
What is a DOT PLOT?
The values that go on the x-axis or horizontal line.
What is the RANGE/SPREAD?
Represented by the box on the graph.
What is the IQR?
The middle of numeric data.
What is the MEDIAN?
Calculated by subtracting Q3 and Q1.
What is IQR?
The shape of a dot plot that has the left and right side of the graph are mirrored images of each other. .
What is Symmetrical?
The values that go on the y-axis or vertical line.
What is the FREQUENCY?
Represented by the middle line in the box.
What is the MEDIAN/Q2?
The spread of the numeric data.
What is the RANGE?
Calculated by finding the median of the lower and upper quartile.
What is Q1 and Q3?
Tells the reader what values are represented in the display (stem and leaf).
What is the KEY?
The major difference between a Histogram and a Bar graph.
What is there are no gaps between the data?
Calculate the MIN, MAX, Q1, Q2, and Q3 for the following data 8, 14, 20, 15, 17, 16, 12, 11, 10, 9, 8, 16.
What is
MIN:8
MAX:20
Q1:9.5
Q2:12
Q3:15.5
82 is the number that represents both of these.
What is the mode, and the range?
Calculate IQR for the data set.
{10, 12, 7, 9, 8, 14, 13, 2}
What is 5?
Describe the benefits of using a dot plot or stem and leaf plot.
What is they separate the data individually instead of in a range?
Shape when the lower values on on the left and ascend upward to the right.
What is SKEWED LEFT?
Calculate the IQR for the following data 8, 14, 20, 15, 17, 16, 12, 11, 10, 9, 8, 16.
What is 6?
