Data Set 1
Rewrite Data Set 1 in a way that is most beneficial to find the median.
28, 32, 40, 31, 33, 39, 27, 42
27, 28, 31, 32, 33, 39, 40, 42
Rewrite Data Set 2 in a way that is most beneficial to find the median.
4, 2, 2, 3, 2, 2, 4, 4, 12
2, 2, 2, 2, 3, 4, 4, 4, 12
Define mode.
The mode is the most frequently occurring number in a data set.
Given the set of data for this category, identify the upper and lower extremes.
4, 6, 7, 10, 10, 3, 1, 9, 5, 9
Upper Extreme = 10
Lower Extreme = 1
What is Miss P's classroom number?
Don't look at the room number outside!
2112
Using Data Set 1, identify the mode if there is one.
No mode
Using Data Set 2, identify the mode if there is one.
Mode = 2
Define mean, or tell me how to find it.
The mean is the average of a set of numbers.
OR
Find the mean by adding all the numbers in a set and dividing by the number of numbers.
Given the data set for this category, find the median.
Median = 6.5
What sport did Mrs. Holloway coach at her old school?
Softball
Using Data Set 1, find the median. If your answer is a decimal, round to the nearest tenth.
Median = 32.5
Using Data Set 2, find the median. If your answer is a decimal, round to the nearest tenth.
Median = 3
What are the "whiskers" in a box & whisker plot?
The whiskers connect the upper and lower quartiles to the upper and lower extremes in a data set.
Given the data set for this category, find the lower quartile (Q1).
Lower Quartile (Q1) = 4
What genre of music do Mrs. Grow and Miss P. both listen to?
K-Pop!
Using Data Set 1, find the mean. If your answer is a decimal, round to the nearest tenth.
Mean = 34
Using Data Set 2, find the mean. If your answer is a decimal, round to the nearest tenth.
Mean = 3.8
How do I find the upper quartile (Q3) in a data set?
First find the median of the data set. Q3 is the median of all the numbers AFTER the median.
Given the data set for this category, find the upper quartile (Q3).
Upper Quartile (Q3) = 9
What is Miss P's BIGGEST classroom pet peeve?
Throwing things
Are there any outliers in Data Set 1? Circle yes or no. If yes, what are they?
No outliers
Are there any outliers in Data Set 2? Circle yes or no. If yes, what are they?
Yes
The outlier is 12.
How can an outlier affect the mean of a data set? For example, if the outlier is LARGER than the rest of the data, what happens to the mean?
Draw the box & whisker plot for this data set.
