If your question refers to the structure of the cards, there are four suits, each with 13 cards:

A,2,3,4,5,6,7,8,9,10,J,Q,K

If your question refers to why these cards were selected, the popular answer is that there are four suits for the four seasons and thirteen cards in each because there are thirteen weeks in a season. As you can see, the 52 cards correspond with the fact that a year has 52 weeks.

Yes.

The mean is 4.25

Anand Mehta said yes and this is correct. You will get a SD, for example, if all of the data points are less than one, or if the data points are very close together and there is not much spread in the data..

Median = 4

Modes = 2 and 4 (the set of values is bimodal).

yes

56 if digits can be repeated.

18 if they can't.

Statistics often requires one to make estimates of some measure (variable) about a set of units. The total number of such units is the population size.

Note that population, in this context, need not refer to people. If the study is about household expenditure on food (in some area), then the population is all households and the population size is the number of households (in that area). If the study is about diversity of insects in a field, the population may be all 1-metre squares in the field, and the size of the population will be the number of such plots - which will equal the area of the field.

Gm = SQRT (9*5) = SQRT (45) = 6.708 (to 3 decimal places)

If you have only one value it is a median itself.

If your finding the average with three numbers on etc'90, 105 120' You'll add them together 90+105+120=315 and divide by three. So the average height will be 105

No. You must have the mean ("average") as well.

Colours are a qualitative rather than a quantitative variable. As a result, a line plot is not an appropriate graphic.
