Measurement of Central Tendancy
Measures of Central Tendency
- A value that represents the center of a data set
- Can be the mean,median, or mode
Data Set - is a number that you must arrange in order from least to greatest
Median - the middle number in a set of data after the data have been arranged in ordereg.
- median of 2,5,6,8,9 is 6
- median of 1, 3, 6, 8, 9, 10 is 7
Mode - the frequently occurring number in a set of data
mode and most have 4 numbers
- mode of 3,5,7,7,9 is 7
- mode of, 2, 4, 6, 6, 8, 11 is 2 and 6
- mode of 1, 2, 3, 5 is no mode
- mode of 1, 1, 1, 2, 2, 2, 3, 3, 3 is no mode
- mode of 1, 1, 1, 2, 2, 2, 3, 3, 3, 4 is 1, 2 and 3
Mean - a measure of a central tendency, the sum of the set of value divided by the number of values in the set (add up all the numbers, divide that by how many numbers there in the set.)
- mean of 6,4,8 is 6
4,6,8
4+6+8=18
Range - The positive between the largest and smallest values in a data set
- range of 1,3,4,5,5,6,6,8,8,9
9 - 1 = 8
- range of -7, -4, -2, -1
(-1) - (-7) = 6
Outlier - a value that is much larger or smaller then the other data value
the data set may have more then 1 outlier or 0 outliers
outliers are 1,67,67,67,65,100 - 1 and 100

Measures of Central Tendency
Measures of Central Tendency
a value that represents the center of a data set
can be the mean, median, or the mode
data set is a group of numbers that you must
arrange in order from least to greatest.
the middle number in a set of data that have been ordered.
Answer
Mode- the most frequently occurring number is a set of data (number that shown up the most)
mode and most both have four letters
Mean- a measure of central tendency
the sum of a set of values divided to the number in the values of set
add up all the numbers. divide that by how many numbers there are.
Range- the positive difference between the largest and smallest values in a data set.
~~~~~
Outliers- a value that is much larger or smaller than the other date value
the data set may have more than one outlier
Find mean, median, mode, range and outliers for the following data set.

Measures of Central Tendency
Measures of Central Tendency
-A value that represents the center of a data set
-Can be the mean,median, or mode
-data set is a group of numbers that must arrange in order from least to greatest
Eg: 2, 3, 4, 5, 6, 5, 4, 5, 3, 4, 5, 6, 7, 5, 34, 3
2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 7, 34
Median- the middle number in a set of data
after the data have been arranged in order
Median of 2 5, 6, 8, 9 is 6
Median of 1, 3, 6, 8, 9, 10 is 7 because if you have 2 numbers in the middle add them up the divide by 2. So 6+8=14/2=7
Solution: Odd = don't add
Even=add
Mode-the most frequently occurring number in a set of data
-mode and most both have 4 letters
-mode of 3, 5, 7, 7, 9 is 7
-mode of 2, 2, 4, 6, 6, 8, 11 is 2 and 6
-mode of 1, 2, 3, 5 is no mode
-mode of 1, 1, 1, 2, 2, 2, 3, 3, 3 is no mode
-mode of 1, 1, 1, 2, 2, 2, 3, 3, 3, 4 is 1, 2 and 3
Mean-a measure of central tendency
the sum of a set of values divided by the number of values in the set
-mean of 6, 4, 8 is 6 because you add them all together then divided by how much numbers there is. So 6+4+8=18/3=6
Range- the positive difference between the largest and smallest values in a data set
-Range of 4, 8, 5, 6, 9, 1, 3, 5, 8, 6, is 9-1=8
Outliers- a value that is much larger or smaller then the other data value
-the data set may have more than 1 outliers or zero outliers
Outliers are 1, 67, 68, 67, 64, 65, 100
