What value do we plot on the y-axis of a graph?
On whichever variable is considered the y-variable. It would be the second element of each ordered pair of data points.
What are the components of a variable?
A variable typically consists of a name, a data type, a value, and a memory location where the value is stored. The name is used to reference the variable in the code, the data type defines the type of data the variable can hold, the value is the actual data stored in the variable, and the memory location is where the value is stored in the computer's memory.
What is the difference between data and variable?
data type refers to the kind of value that is held by a particular variable. For ex: an int variable contains integer value, a string holds a alpha numeric value etc. variable refers to the name of a value using which we can refer to this value. Ex: public int age = 28; here int is the data type and age is the variable.
What defines a variable?
A variable is a named storage location that can hold any data value. A variable has two associated values ; r value and l value.
Does a variable only have one numerical value?
Not necessarily.A variable can hold other types of values, not just numbers. For example, a variable can hold a date, a text (also know as "string"), a boolean (true or false) value, etc. In object-oriented programming, you basically make up your own data types.An array variable can hold several related values. The individual values are usually distinguished by a number, called a subscript. (In other words, you have the first element, the second element, etc. in the array.)
What defines a data type?
the type of data which we store in a variable.. example: int a=10; /*here a is variable (data) which is of type int and stores a value 10.*/
What is the name of a storage location that can hold a data value?
A variable is a named storage location that can hold a data value in a program.
What are the measurements of observations for a variable called?
data
What values do we plot on the y - axis of a graph?
On whichever variable is considered the y-variable. It would be the second element of each ordered pair of data points.
Is it true that passing data by reference enables you to change the value stored in a variable in one file using a function in another file?
Yes, passing a variable by reference gives you a pointer to the original variable, meaning you can change its value from within the function being called and the change will affect the original variable.
If a variable is not initialized the value of that variable is likely to be?
It's almost impossible to predict, but the value will be some data left by OS when it was previously used.
What is a set of data with one variable called?
Univariate.
