Mean, Median, Mode
This measure is found by adding all numbers and dividing by how many you have.
Mean
A dot plot shows data using these small marks above a number line.
Dots
In the value 47, which digit is the stem?
4
MAD stands for Mean ________ Deviation.
Absolute
6 x 7
42
The middle number in an ordered set of data.
Median
A dot plot shows data using these small marks above a number line.
Histogram
A stem-and-leaf plot organizes numbers by their tens and these units.
Ones (units) digits
MAD measures how far data points typically are from this measure of center
mean
12 x 4
48
In the set {2, 2, 3, 5, 7}, this is the mode
2
If a dot plot has several dots far from the others, what do we call those unusual points?
Outliers
A stem-and-leaf plot organizes numbers by their tens and these units.
Least to greatest
If all numbers in a set are the same, the MAD equals this.
0
18 x 9
162
A set has two modes. What do we call it?
Bimodal
In a dot plot, the number with the most dots represents this measure of center.
Mode
The stem-and-leaf plot shows leaves: 2, 4, 7 on stem 3. Name one number represented.
32, 34, or 37
To find MAD, we first find this measure, then calculate distances from it.
The Mean
27 x 13
351
The median of {4, 7, 9, 12} is found by taking the mean of these two numbers.
(7 + 9) รท 2 = 8
A histogram is different from a bar graph because these two features touch each other.
Bars (bins) touch each other
When combining two classes' plots into one, this type of stem-and-leaf plot is created.
Back-to-back stem-and-leaf plot
A larger MAD means the data is more this.
Spread out (more variability)
