How do you work out the avarge in maths?
The average is the sum of all of the numbers in a data set DIVIDED by the number of numbers in the data set. Therefore, given the following set of numbers 5 5 7 8 10 The average would be (5 + 5 + 7 + 8 + 10) / 5 which will give you 7. so the average is 7
Tell when a set of data can have no mode?
A set of data has no mode when there is no number that occurs more frequently than another. The data set: 1, 2, 5, 5, 6 has a mode of 5. The data set: 1, 2, 3 has no mode.
What is the variance of 3 15 2 5 5?
The variance is 27.0
What is the range and mean of a set of numbers?
The mean is all of the numbers in the set of data added up then divided by how many numbers are in the set of data. It is also called the average. The range is the highest number in a set subtracted by the smallest. mean: Range: 2,4,10,and 5 2,4,10 and 4 2+4+10+4=20 10-4=6 20/4=5
What is a bimodal data set?
A bi-modal data set is a data set that has two modes. In the data set 1, 2, 2, 3, 4, 4, 5 the mode is 2 AND 4. So it is a bi-modal data set. Hope that helps.
What is the variance of the data set of 18 14 10 9 5?
- 4
What is the variance with sample data set 10 8 8 6 5?
Sum(X) = 37 Sum(X2) = 289 Var(X) = Sum(X2) - sum(X)2/n = 289 - 37*37/5 = 15.20
A fair coin is tossed 10 times what are the expected mean and variance of the number of heads?
mean = 5, variance = 5
What is the range and standard deviation when the variance for a set of scores is 25?
5
How do you get the range in math?
Subtract the smallest number in the data set from the largest number in the data set. eg, the range of {3, 1, 5, 6, 6 ,8, 10, 5, 8} is 10 - 1 = 9

What is the mean in a set of data?
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
Tell when a set of data can have no mode?
A set of data has no mode when there is no number that occurs more frequently than another. The data set: 1, 2, 5, 5, 6 has a mode of 5. The data set: 1, 2, 3 has no mode.
What is the variance of 3 15 2 5 5?
The variance is 27.0
How do I Merge data in SAS?
Use the merge command. For example: Data set one ID A B 10 1 2 20 3 4 30 5 6 Data set two ID C 10 0 20 5 30 7 data three; merge one two; by id; run; Output: ID A B C 10 1 2 0 20 3 4 5 30 5 6 7
What is the most reasonable interval for the data 5 10 30 40 20?
A good way to assess what is a reasonable interval when graphing data is to see if there are any common factors in the data set. In this case 5, 10, 30, 40 and 20 are all clearly divisible by 5. Therefore, 5 would be a reasonable interval to use when graphing the data.
Finding the range in a set of data?
The range of a set of data is the difference between the largest and smallest, ie subtract the smallest from the largest. For example:Find the range of the data {10, 20, 50, 17, 89, 24, 5, 56}The largest is 89 and the smallest is 5, so the range is 89 - 5 = 84.
