agreed, what also adds to the confusion is mathematic's liberal use of the word norm .. as a scalar (square root of sum of the squares) , norm as a vector normal to the plane, or a series as the normal distribution. Mathcad itself can not take all the blame
And more! In Mathcad Prime! If elements of vector have different dimension can we say that it is a vector!? This construction must have other name? not a vector (or matrix). A set of values? A vector is a set of values with same dimention (length!).

I would just call it an "array". In this case, a single column array.
"A single column array" 
One joke.
Do you know that John is (an) Ambidexter?
Who?
John!
An engineer points that it is a vector, a mathematician - not a vector! See my start message!
OK!
I studied same Math in my University too.
What is it - a scalar or a vector or a matrix or a single column or a single row

As far as Mathcad is concerned, it's a single element array--if you try to address it as a scalar Mathcad will take offense.
As far as I'm concerned, I'm like the accountant:
A businessman was interviewing candidates for head accountant. He presented the first candidate with a balance sheet and asked, "What were my profits?" After several minutes of calculations, the man gave him an answer. The second man, presented with the same information and asked the same question took twice as long to compute a slightly smaller answer. When the third candidate was presented with the same problem the response was immediate, "Whatever you want it to be!"

And other jole:
The guests are gone and the wife tells her husband: You told John that he was right. But you told Sam that he is also right. But John and Sam have had the opposite opinion. How can this be?! The husband thought about it and said, and you, my dear, are right!
We have in Mathcad two tools in one box - a vector/matrix/tensor and an 2D/3D/Nested array.
When we work with any vector/matrix we must have ORIGIN=1
When we work with any array we must have ORIGIN=0
One typical vector by solving in Mathcad one physical problem:
One typical not vectors but 2D array (a simple colomn array):

Sorry,
I think that a classic vector can have different dimensions too. See one typical simple task from a linear algebra bellow (True, the unit for mathematicians - is like a red rag to a bull!).
