• 1. Data Landmarks

2. Identify the maximum, minimum, range, median, mode, and mean for a data set

• Maximum
• Minimum
• Range
• Median
• Mode
• Mean

• This is the highest value in a data set.

96, 94, 98, 90, 94, 85 The maximum for this set of data is 98 because it is the highest value. Try One! 4. Find the maximum for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72,89

98 99 100 95 5. Correct!

• Themaximumfor the data set :

98, 94, 97, 95, 95,99 , 92, 85, 72, 89 is 99 because 99 is the highest value in the set. Click here to return to the main menu! 6. Keep Trying!

• Themaximumfor the data set :

98, 94, 97, 95, 95,99 , 92, 85, 72, 89 is 99 because 99 is the highest value in the set. Click here to return to the main menu! 7. Minimum

• This is the smallest value in a set of data.

96, 94, 98, 90, 94, 85 The minimum for this set of data is 85 because it is the lowest value. Try One! 8. Find the minimum for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72,89

98 99 72 61 9. Correct!

• Theminimumfor the data set :

98, 94, 97, 95, 95, 99, 92, 85,72 , 89 is 72 because 72 is the lowest value in the set. Click here to return to the main menu! 10. Keep Trying!

• Theminimumfor the data set :

98, 94, 97, 95, 95, 99, 92, 85,72 , 89 is 72 because 72 is the lowest value in the set. Click here to return to the main menu! 11. Range

• This is the differencebetween the highest and lowest values in a data set.

96, 94, 98, 90, 94, 85 The range for this set of data is 8 because the maximum (98) minus the minimum (90) = 8 Try One! 12. Find the range for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72, 89

16 27 10 18 13. Correct!

• Therangefor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 27 because 99 (max) 72 (min) = 27 Click here to return to the main menu! 14. Keep Trying!

• Therangefor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 27 because 99 (max) 72 (min) = 27 Click here to return to the main menu! 15. Median

• This is the middle value in a set of data.

The median for this set of data is 94 because it is the middle value. 85, 90, 94, 94, 96, 98 Try One! Dont forget to put the data in order from least to greatest first! 16. Find the median for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72, 89

94 97 94.5 95 17. Correct!

• Themedianfor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 94.5 because it is halfway between the two middle values. (You will only do this when there is an even number of values.If the number of values is odd, the median is the number in the middle.) Reorder the values: 72, 85, 89, 92,94, 95 , 95, 97, 98, 99 94 + 95 = 189; 189 / 2 = 94.5 Click here to return to the main menu! 18. Keep Trying!

• Themedianfor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 94.5 because it is halfway between the two middle values. (You will only do this when there is an even number of values.If the number of values is odd, the median is the number in the middle.) Reorder the values: 72, 85, 89, 92,94, 95 , 95, 97, 98, 99 94 + 95 = 189; 189 / 2 = 94.5 Click here to return to the main menu! 19. Mode

• This is the value that occurs the most frequently.

The mode for this set of data is 94 because it occurs the most often. 85, 90, 94, 94, 96, 98 Try One! 20. Find the mode for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72,89

95 97 99 92 21. Correct!

• Themodefor the data set :

98, 94, 97,95 ,95 , 99, 92, 85, 72, 89 is 95 because 95 is the value that occurs the most often. Click here to return to the main menu! 22. Keep Trying!

• Themodefor the data set :

98, 94, 97,95 ,95 , 99, 92, 85, 72, 89 is 95 because 95 is the value that occurs the most often. Click here to return to the main menu! 23. Mean

• This is the value that occurs when you combine all of the values and divide them evenly.

The mean for this set of data can be found by: finding the sum of the values = 557 Dividing by the total number of values = 557 / 6= 92.83 85, 90, 94, 94, 96, 98 Try One! 24. Find the mean for the following data set:

• 98, 94, 97, 95, 95, 99, 92, 85, 72, 89

95 91.6 99 90 25. Correct!

• Themeanfor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 91.6 because when you add the values together and divide them equally (find the sum of all values and divide it by the total number of values) you get: 98 + 94 + 97 + 95 + 95 + 99 + 92 + 85 + 72 + 89 = 919 916 / 10 =91.6 Click here to return to the main menu! 26. Keep Trying!

• Themeanfor the data set :

98, 94, 97, 95, 95, 99, 92, 85, 72, 89 is 91.6 because when you add the values together and divide them equally (find the sum of all values and divide it by the total number of values) you get: 98 + 94 + 97 + 95 + 95 + 99 + 92 + 85 + 72 + 89 = 919 916 / 10 =91.6 Click here to return to the main menu! 27. Find the max, min, range, mean, median, and mode of the following data set:

• 91, 96, 97, 92, 94, 90, 90, 98, 99, 100

max= 100 min= 90 med= 95 mean= 94.7 mode= 90range = 10max= 100 min= 90 med= 94 mean= 95 mode= 90 range = 6 max= 100 min= 90 med= 96 mean= 94 mode= 90 range = 10 max= 100 min= 90 med= 95 mean= 95.7 mode= 90 range = 4.3 28. Correct!
