Mean
What is the formula of mean?
Sum of terms/
Number of terms
What do you do if their is not one middle number?
You find the middle of those numbers to decide the median.
What is the explanation if theirs no number higher than the data set or an equal high number?
If theirs no highest number or number more than once than their is simply no mode. If theirs more than one highest number than their can be multiple modes.
Does range change if their are double or more numbers in the data set?
No the range does not change.
How is mean similar to mean of absolute diviation?
Mean is simply the mean of all the numbers in the data set while mean of absolute diviation is the mean of smaller parts of smaller parts of the data set.
What is mean in statistics?
The middle or average.
What is median in statistics?
The "middle" of a sorted list of numbers.
What is mode in statistics?
The number that shows up the most in the data set.
What is range in statistics?
The difference between the lowest and highest number in the data set.
What is the mean of absolute deviation in statistics?
The average absolute deviation, or mean absolute deviation, of a data set is the average of the absolute deviations from a central point.
What is the mean of numbers:
3,5,5,6,8,10,11,11,13
The mean is 8.
What is the median of these numbers:
10,11,11,13,15,16,16,16,17,18,19
The median is 16.
What is the mode of these numbers:
1,1,2,3,4,4,4,5,5,6,7,8,8,9,10
The mode of this data set is 4.
What is the range of the numbers:
12,12,13,14,14,14,15,16,17,17,18,18,18,20
The range is 8.
Find the mean of absolute deviation for these numbers:
1,1,2,3,3,3,4,5,8,8,9,10,11,11
Mean: 5.64
Lower mean of diviation: 2.43
Higher mean of deviation: 8.86
What are the steps to finding mean?
First add all numbers together then divide that number by the number of numbers that were given.
What are the steps to finding median?
First put all the numbers in smallest to largest, then crosscut numbers from both sides to find the middle number.
What are the steps to finding mode?
All you have to do is find the number that occurs most in the data set.
What are the steps to finding range?
Subtract the highest number from the lowest number.
What are the steps to finding mean of absolute diviation?
First find the mean of all the numbers in the data sets then find the mean of two half parts of the data to find absolute deviation.
How is mean and mean of absolute deviation different?
The Mean Absolute Deviation (MAD) of a set of data is the average distance between each data value and the mean. The mean absolute deviation is the "average" of the "positive distances" of each point from the mean.
How is median and mean different?
Mean is what you get from adding all the numbers nd then dividing to find the middle while median is where you line the numbers up smallest to largest and find the middle number.
How is the mode different from the amount of all numbers in the data set?
Mode is only the number that occurs most so not the amount of all the numbers.
How is range different from the highest number in the set?
The range is the number value from the lowest to highest number not the highest amount present in the data.
True or False:
Their are always more than one answer to mean of deviation.
True because mean of absolute deviation are the means of several parts of the data set. Only one answer would only be the mean.
