Is the number of pregnancies a woman has had an example of discrete or continuous variable?

Discrete. You can't have 1.5 pregnancies. Or anything between 1 or 2. If you have had 1, your next is 2.

Example of nominal variable and real variable?
A nominal variable is one where observations are classified to categories eg small, medium and large for t-shirts. A real variable is one that takes numerical values, such as shirt size 12, 14, 16 etc. A real value may be a continuous (as opposed to discrete) variable but the very act of recording the observation usually results in the continuous variable being replaced by a discrete one.
What is a example of discrete data?
Discrete data are observations on a variable that which take values from a discrete set.
How can you identify continuous variables on a line graph?
With great difficulty. This is because if the variable is recorded by people, it will be rounded. That process will make it discrete - even if the underlying variable is continuous.For example, time is a continuous variable, but time is normally recorded in seconds. At track events it may be measured in hundredths of seconds and in some labs in much smaller units. Nevertheless it will always be in discrete "chunks".
What is the difference among non-orderable discrete orderable discrete continuous variables?
A non-orderable discrete variable is usually one for which the information that is recorded can only have a finite number of qualitative outcomes and that there is no relevant ordering of these outcomes. One example might be favourite fruit. Although the responses can be ordered alphabetically, or by mass of typical specimen, these are not relevant ordering schemes. An orderable discrete variable is one in which there is a relevant basis for ordering the outcomes. An example might be shoe sizes which, in the UK, go ... 6.5, 7, 7.5, 8, 8.5, 9, ... .The ordering reflects how large the shoe is. A continuous variable is one which can take any possible value in the permitted range. A typical example is a person's height. Even though in recording the variable becomes discretised (eg 5ft 10" or 176 cm), the underlying variable is continuous.
Is a proportion an example of a continuous variable?
No
The amount of time needed to run the Boston Marathon is an example of which type of variable?
A continuous variable which is made discrete when recorded.
Difference between continuous and discrete variables?
Continuous variable is one like temperature, and discrete variable are ones like male and female. So if you are looking at temperatures between 90 and 100 degrees, there is an infinite number of them. Say between 99 and 99.1, we have 99.05 and between that and 99 we have 99.005 etc. The variable is continuous because it can take on any value between 90 and 100. But if you are talking about gender, than it is either male of female and not continuous. Having said all this, now we define a continuous variable A continuous is one for which, within the limits the variable ranges, any value is possible. So what about time? If the variable is how long it take to read this answer, is that discrete? NO, it is continuous. A five point scale is an example of a discrete variable.
Is height a discrete or continuous variable?
its continuous because if it was discrete i could measure it right now but its actually over time. For example: if my doctor wants to weigh me ,he will weigh me once and then weigh me again in like 1 week or so
What is a discontinuous variable?
A discontinuous variable is a variable that has distinct categories. Blood type is a good example. You could be A, B, AB or O. This contrasts with a continuous variable such as height or weight, where there are an almost infinite number of possible values. Data for discontinuous variables is usually represented using a bar graph or pie chart, but never a scatter graph.
What is a dicrete variable?
A discrete variable is a variable that has a certain set limit. For example, a ten point scale can ONLY have the variables 1, 2, 3, 4, 5, 6, 7, 8, 9, & 10. 2.8 would not work on a discrete variable ten point scale. Height is an example of a continuous variable, or one that has an infinite possibility.
What does discrete mean in algebra?
In basic algebra a discrete variable is one that can only take on specific set of values. For example, if we were to say that X can only take on a whole value between 1 and 10, then X would be a discrete variable. On the other hand, a continuous variable is one that can take on an unlimited number of values. For example, if we were to say X can take on ANY value between 1 and 10, then X is called a continious variable. The important thing to note is that the range of a variable (the min and max values it can take) is different than whether it is discrete or continuous. Discrete only implies a fixed (and known) set of values is possible for a variable
Is temperature an example of continuous variable?
Yes. It is a continuous variable. As used in probability theory, it is an example of a continuous random variable.

Is the variation in weight in human populations an example of discrete or continuous variation?
It is an example of continuous variations.
