No, for example the set of data 15,20,26,28 has a median that is 20 + 26 /, or 23

Is it true that in large data sets the mean is always one of the data values?
No. Here's one set of data where the mean is not one of the values: a set of 250,000 numbers. 125,000 of them are "1", 125,000 are "3". The mean of this data set is "2", which is not among the data.
What is a correlation where one set of data values increases as the other decreases?
one set of data values increases as the other decreases
How do you find the missing value if the mean of the data set is 5 here is the problem 3 8 4 1 3?
There are five values with one missing. The original set had six values with a mean of 5, which means that the members of the set added up to thirty. The values we have total 19, the missing value is 11.
In any data set are the median and mean usually very similar in value?
yes they are if you have 0 and 10 the mean is 5 and so is the median. The mean and the median can in fact be the same value. But basically to answer your question, One possible way is that if the values are ascending by 1 in the data set, then the number of values left to the median should be the same as the number of values right to the median. e.g. 6+7+8+9+10 6,7 = 2 terms 9,10 = 2 terms median =8 mode = 8
What is one variable data What is two variable data?
One variable data are measurements or recordings of the values of one characteristic of the subjects which are being studied. Two variable data refer to two characteristics. Examples of one variable data: hair colour, or height Examples of two variable data: hair colour and eye colour, or height and mass.

Does the mean have to be one of the data values?
Not all the time
What percentage of data values of a normal distribution will fall within one standard deviation below the mean?
34.1% of the data values fall between (mean-1sd) and the mean.
How mean of a data set is always one of the data points in a set of data. Explain?
The mean of a set of data is the sum of all those data values, divided by the numbers of values in the set. For instance, if we had 1, 3 and 5, the mean would be (1+3+5)/3 = 3. The mean doesn't always have to be one of the data points in the set. For instance, if we had the data 1, 6, 7, 7, 8. The mean would be (1+6+7+7+8)/5 = 5.8, even though 5.8 isn't one of the values in the set.
A set of 1000 values has a normal distribution the mean of the data is 120 and the standard deviation is 20 how many values are within one standard deviaiton from the mean?
The Empirical Rule states that 68% of the data falls within 1 standard deviation from the mean. Since 1000 data values are given, take .68*1000 and you have 680 values are within 1 standard deviation from the mean.
The hyperlink data type stores data that can have one of two values?
yes/no data type stores only one oftwo values
What is a correlation where one set of data values increases as the other decreases?
one set of data values increases as the other decreases
What does analogue data mean?
Analogue data is data in a continuous stream that has an infinite range of values that change gradually. One example of analogue data is the sound of a person talking. We are capable of handling analogue data, yet computers require analogue data to be converted into digital data for processing.
What happens to the mean of a data when you add values that cluster near one end of the original data set?
I'm not completely sure what you mean. But I can tell you how to find the mean, if that is what you are looking for. You must add up all your numbers (4+2+1) and then take you answer and divide it by the number of numbers you added together (7 divided by 3) The quotient is your answer. Hope I was a help
Advantages and disadvantages of mean in statistics?
MEDIANUse the median to describe the middle of a set of data that does have an outlier.Advantages:• Extreme values (outliers) do not affect the median as strongly as they do the mean.• Useful when comparing sets of data.• It is unique - there is only one answer.Disadvantages:• Not as popular as mean.
When creating a Chart in Excel a multiple date series is?
A data series is a range of values to be charted. If you have multiple data values, you may have multiple series, like several lines on a line chart. So you can have lots of values in a series, and lots of series in some charts. A pie chart cannot have more than one series.
