Yes, there can be two means in a set of data if the data is divided into two distinct groups or populations that have different characteristics. Each group would have its own mean, and the overall set of data could have a mean that is the average of the means of the two groups.

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 does pooled data set means?
is a data set with same variables but observed from different group of respondents
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 does the word rank mean in data sets?
It means the position [of an observation] in an ordered data set.
What does it mean to have 95 percent confidence in an interval estimate?
It means that 95% of the values in the data set falls within 2 standard deviations of the mean value.
What does bimodal mean?
It means it has two modes.
What a small MAD tell you about a data set?
It means that there is little variability in the data set.

Can there be 2 outliers in a set of data?
There is no limit to the number of outliers there can be in a set of data.
Can there be 2 modes in a data set?
There can be two modes in a data set. For example, in the data set {0,1,2,3,3,4,5,5,9}, there are two modes: 3 and 5.
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.
Can there be more than 2 modes in a data set?
Yes there can be more than 2 modes in a data set. It is called multimodal.
The range of a set of data is 48 If the lowest value in the data set is 2 what is the highest value?
50
Is the number of permutations of 2 items from the same data set always 2 times the number of combiations when taking 2 objects from a data set?
Yes
What does the word rank mean in data sets?
It means the position [of an observation] in an ordered data set.
Can the median of the data set be the same as Q1 and Q3?
Yes. An example: the data set {1, 1, 2, 2, 2, 2, 2, 2, 2, 3, 5} has median = Q1 = Q3 = 2.
