Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |

| 2Ages: 10, 11, 10, 11, 45 | B=MAX(B2:B8) | |
| 3Finding the highest value in a set of data | CA trend going up, because each number is bigger than the one before | |
| 4Finding the lowest value in a set of data | DThe number 45 is an outlier because it stands out from the rest | |
| 5Temps: 20, 22, 24, 26 - 'The trend is going down.' | EThe numbers get bigger each time, so the trend is going up, not down. | |
| 6Class A average 8, Class B average 6 - 'Class B scored higher.' | FClass A has the bigger average, so Class A scored higher when comparing the groups. |

Answer Key
Finding patterns, trends and outliers
Section A: Quick Questions
Q1
A — The temperature is going up
Q2
A — 42
Q3
B — 10
Q4
B — A value that is very different from the rest of the data
Q5
A — Class 5A read more books than Class 5B
Section B: Match the Pairs
Q1
Sales: 5, 8, 12, 15 → A trend going up, because each number is bigger than the one before
Q2
Ages: 10, 11, 10, 11, 45 → The number 45 is an outlier because it stands out from the rest
Q3
Finding the highest value in a set of data → =MAX(B2:B8)
Q4
Finding the lowest value in a set of data → =MIN(B2:B8)
Q5
Temps: 20, 22, 24, 26 - 'The trend is going down.' → The numbers get bigger each time, so the trend is going up, not down.
Q6
Class A average 8, Class B average 6 - 'Class B scored higher.' → Class A has the bigger average, so Class A scored higher when comparing the groups.
Section C: Definitions
Q1
pattern, trend, outlier — Look for patterns and trends in data, like highest, lowest, going up or down. An outlier is a value that stands out from the rest. Compare groups to see differences.Section D: Fill in the Blanks
Q1
Highest score: =MAX(B2:B8)Q2
Lowest score: =MIN(B2:B8)Q3
Data: 4, 5, 6, 5, 50
The number 50 is an outlierQ4
Scores: 3, 5, 7, 9
The trend is going upQ5
Class A: =AVERAGE(B2:B8)
Class B: =AVERAGE(C2:C8)Section E: Spot the Error
Q1
D — The outlier is the value that stands out from the rest. In this list that is 20, not 4. It should be outlier = 20.
Q2
B — The temperatures get bigger each time, so the trend is going up. It should be trend = 'going up'.
Q3
B — To compare groups fairly, both groups must be measured the same way. avg_b uses AVERAGE, so avg_a should be AVERAGE(class_a).
Q4
D — The gap between the highest and lowest values is found by subtracting. It should be gap = wettest - driest.
Q5
A — The outlier is 30, but the list no longer contains 30, so nothing stands out. The list should include 30: [8, 9, 7, 30, 8].
