What else can I help you with?
When can the mean be the largest value in the data set?
When the data set consistys of a single value.
What is the least value of the data set?
The least value of the data set is called the minimum.
Can the mean be greater than the greatest value in the data set?
No, the mean cannot be greater than the greatest value in a data set. The mean is calculated by summing all the values and dividing by the number of values, which means it will always fall within the range of the data set. Therefore, the mean will always be less than or equal to the maximum value.
What is meant by the standard deviation of a data set?
It is a measure of the spread of the data around its mean value.
Definition of mean median and mode?
Mean is the average of the data set values. Median is the middle number in the data set (set up in ascending or descending order). Mode is the data value (or values) that occur the most number of times.
When can the mean be the largest value in the data set?
When the data set consistys of a single value.
What is the least value of the data set?
The least value of the data set is called the minimum.
What is a value much greater or much less than the others in a data set?
A value that is significantly higher or lower than the other numbers in a set are called extremes. They are sometimes excluded from calculations like the mean (average) but sometimes they are included.
Can the mean be greater than the greatest value in a data set?
No.
A data set has 9 values The mean of the set is 5 When a tenth value is added the mean becomes 6 What is the tenth value?
15
Can the mean be greater than the greatest value in the data set?
No, the mean cannot be greater than the greatest value in a data set. The mean is calculated by summing all the values and dividing by the number of values, which means it will always fall within the range of the data set. Therefore, the mean will always be less than or equal to the maximum value.
What is meant by the standard deviation of a data set?
It is a measure of the spread of the data around its mean value.
Why is it helpful to find the mean of a data set?
It is one of the key measures of a data set: it shows the value around which the observations are spread out.
Can there be more than one mean in a set of numbers?
No. But there can be more than one data point which has the same value as the mean for the set of numbers. Or there can be none that take the mean value.
Would you use mean mode median to average the points?
mean is the average of numbers in the data set mode is the most frequently occurring value in a data set and median is the middle number of the data set so you would use mean
What value shows how the data set as a whole is spread around the mean?
variance
What is the minimum data value in a data set?
The minimum data value in a data set is simply the lowest value of the set (easily found by arranging the set from lowest-highest values in an excel sheet or by hand).
