The 20 questions
-
How do you calculate the mean of a set of readings?
- Subtract the lowest reading from the highest reading
- Add all the readings together, then divide by how many readings there are
- Find the reading that appears most often in the set
- Put the readings in order, then take the middle reading and write it down in your book
-
What is the median of a dataset?
- The middle value when the numbers are put in order
- The value that appears most often in the dataset
- The difference between the highest and lowest values
- The total of all the values divided by their count
-
What is the mode of a dataset?
- The value that appears most often in the dataset
- The middle value when the numbers are placed in order
- The difference between the highest and lowest values
- The total of all the values divided by how many there are
-
How do you calculate the range of a dataset?
- Subtract the lowest value from the highest value
- Add the highest value to the lowest value
- Find the value that appears most often in the set
- Divide the highest value by the lowest value
-
Find the median of 3, 5 and 9.
- 5
- 3
- 17
- 9
-
Find the range of 14, 20 and 26.
- 6
- 12
- 40
- 20
-
What kind of correlation is 'as X rises, Y rises'?
- Negative correlation
- Anomalous correlation
- Positive correlation
- No correlation
-
What does a scatter graph with no correlation look like?
- Points all lying on one single horizontal line
- Scattered points with no clear trend or line
- Points falling neatly from top-left to bottom-right
- Points rising neatly from bottom-left to top-right
-
A noise reading of 30 dB sits far below the rest of the set. What is it called?
- An anomaly
- A median
- A correlation
- A range
-
Why can one anomaly distort the mean?
- It makes the range of the dataset become zero
- It is always the value that appears most often in the set and the middle of the data
- It is far from the others, so it pulls the mean up or down
- It changes the order of the numbers so the median moves
-
Calculate the mean of 6, 8 and 10.
- 24
- 10
- 8
- 6
-
Find the median of 4, 6 and 8.
- 6
- 18
- 8
- 4
-
Find the mean, median and range of the values 4, 6, 6 and 8.
- Mean 5, median 6, range 4
- Mean 6, median 8, range 2
- Mean 6, median 6, range 4
- Mean 6, median 6, range 8
-
A river's width is 1.6 m at 0 km and 4.7 m at 5 km downstream. Which correlation does this show?
- Negative correlation, because the width is always smaller at the mouth
- Positive correlation, as distance downstream rises the width rises too
- No correlation, because the two values are different
- Negative correlation, as distance downstream rises the width falls
-
As distance from a city rises, land value falls. What type of correlation is this?
- No correlation
- Positive correlation
- Anomaly correlation
- Negative correlation
-
Shoe size is compared with maths test score for a class. What type of correlation is usually expected?
- Positive correlation
- No correlation
- Strong positive correlation
- Negative correlation
-
Footfall falls from about 180 near the station to about 40 far away. What is the correlation?
- No correlation, because footfall values are always large
- Positive correlation, because the station is the largest place
- Positive correlation, as distance from the station increases footfall increases
- Negative correlation, as distance from the station increases footfall decreases
-
Which is a good way to describe the strength of a correlation on a scatter graph?
- The more colours on the graph, the stronger the correlation, so use bright colours always
- The closer the points lie to a straight line, the stronger the correlation
- The more points on the graph, the weaker the correlation
- The larger the range, the stronger the correlation
-
Why can a strong correlation not prove that one variable causes the other?
- Strong correlations never occur in real geographical data
- Correlations are always calculated using the median only
- Two variables can be linked without one causing the other
- Scatter graphs can only show data from one single site
-
Which measure shows how spread out a set of values is, from lowest to highest?
- The median
- The mean
- The range
- The mode
