Unit 1 Statistics

1. Absolute Deviation is the average distance each number in a data set is from the mean.
4. Plot a visual display that shows the five-number summary of a set of data.
6. Plot is a visual display in which each piece of data is represented by a dot above a number line, showing the frequency of each data value.
8. Range is the distance between the quartile 3 and quartile 1 of a data set.
11. is the average of the numbers: add up all the numbers, then divide by how many numbers there are.
12. a graph is symmetrical when one half is a mirror image of the other half.
14. Quartile (Q1 is the median of the lower half of the values, 25%
15. left means the tail of the distribution is longer on the left side of the graph.
16. is a section in a dataset or graph where no observations or values exist.
18. is where data points are grouped together.

1. is the middle of a sorted list of numbers: place the numbers in value order and find the middle.
2. Questions are questions that have more than one possible answer.
3. is the number that occurs in a data set the most amount of times.
5. is a value that “lies outside” (is much smaller or larger than) most of the other values in a set of data.
7. Graph is the graphical representation of numerical data by rectangles (or bars) of equal width and varying height.
9. is the distance between the highest and lowest data point.
10. Quartile (Q3 is the median of the upper half of the values, 75%
12. right means the tail of the distribution is longer on the right side than of the graph.
13. s a graphical representation that organizes a group of data points into user-specified ranges and is made of bars of equal width.
17. is the highest part on the graph. (Highest frequency)
