A one variable data table has only one input cell and many result cells. ... A two-variable data table has two input cells, but only one result cell. Use a two-variable data table to see how two factors—different interest rates and loan terms—affect a loan payment, for example.

The main difference between 1D and 2D array is that the 1D array represents multiple data items as a list while 2D array represents multiple data items as a table consisting of rows and columns. A variable is a memory location to store data of a specific type.

There are two types of variables: global variables and local variables. The scope of global variables is the entire program whereas the scope of local variable is limited to the function where it is defined.

There is no difference between a variable and a data type. A data type is a type of data, e.g. int for integer, i.e. whole number, String for text, double for precise decimal numbers and so on. A variable is an instance of a data type. ... String s = “String value”; // Where variable s is of data type String.

One-way ANOVA has one continuous response variable (e.g. Test Score) compared by three or more levels of a factor variable (e.g. Level of Education). Two-way ANOVA has one continuous response variable (e.g. Test Score) compared by more than one factor variable (e.g. Level of Education and Zodiac Sign).

2. A one-way ANOVA only involves one factor or independent variable, whereas there are two independent variables in a two-way ANOVA. ... In a one-way ANOVA, the one factor or independent variable analyzed has three or more categorical groups. A two-way ANOVA instead compares multiple groups of two factors.

Remember that variables are items which can assume different values. A function tries to explain one variable in terms of another. Consider the above example where the amount you choose to spend depends on your salary. Here there are two variables: your salary and the amount you spend.

A type (or data type) defines the structure of data that will be stored in an object (variable) of that type. A variable is a named instance of that data type.

2 Answers. A one dimensional array is an array for which you have to give a single argument (called index) to access a specific value. A two-dimensional array is simply an array of arrays. So, you have to give two arguments to access a single value.

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. Why just one?

A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item. ... It is called a variable because the value may vary between data units in a population, and may change in value over time.

Strictly speaking, it is a discrete variable, given that there is a basic unit of 1p below which measurements cannot be taken. However, 1p is so small in relation to an annual salary (even the annual salary of a teacher) that in practice it is treated like a continuous variable.

In other words, a variable in a python program gives data to the computer for processing. Every value in Python has a datatype. Different data types in Python are Numbers, List, Tuple, Strings, Dictionary, etc. Variables can be declared by any name or even alphabets like a, aa, abc, etc.
