This is the value in a sample with as many other values to one side of it as to the other. In other words it is the middle value having no regard to magnitude.

It is a measure of central tendency, and is used mainly in comparison with the mean value, to estimate skewness, although it is not always reliable in this regard.

Mean: the arithmetic average = total of values/ number of values

Median: that value with as many to one side as on the other (might be the mean of the 2 middle values)

Mode: the most often occurring value (might be more than one mode)

a<b<c

**The sign < means less than**

Read from left to right the expression a<b<c means the value of a is less than that of b, and the value of b is less than that of c. In full is means that the value of b falls between the values of a and c.

At least two meanings.

**In statistics** ( say 1-var), let Xmin be the smallest value in the data set, and Xmax the largest value in the set.

**Range= Xmax-Xmin**

**In functions and graphes**

Let y=f(x) be a function, x is the independent variable and y the dependent variable.

The**domain** of the function is the set of all possible values that the independent variable can have: it is the pool where x takes it values, and the function f(x) its inputs.

The**range** of the function f(x) is the set of all possible values of the dependent variable, the set of all possible outputs of the function f(x)

Let y=f(x) be a function, x is the independent variable and y the dependent variable.

The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of {3, 5, 9} is 5). If there is an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values. It is similar to an average. or a root mean square value (RMS).

The question is incomplete.

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

**To find the median: **

Data values 12.5, 13, 13., 13,**13.5**, 14, 19.5, 19.5, 20

**Mean** =(12.5+13+13+13+13.5 +14+19.5+19.5+20)/9=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

**Median**=13.5

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

**Mean** =(12.5+13+13+13+**13.5** +**14**+19.5+19.5+20 + 25)/10=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

**Value of Median** =(13.5+14)/2=?

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

- Order the data values in ascending order (sort them from the smallestr to the largest), and
- Locate the data value that is in the middle.
- If the number of data values id ODD (not a multiple of 2) there is only one middle element. That is the median.
- If the number of data elements is EVEN (multiple of 2), there is not one middle element but two.
- The median is the average of the two middle element values
**Median =( left of middle value +right of middle value)/2****Imagine this median value to be inserted between the two middle elements**

Data values 12.5, 13, 13., 13,

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

If the parabola has its concavity turned downward and it maximum value is lower than 0 then the value of the functions are always negative (never reach 0).

Similarly, if the parabola has it concavity turned upward, and its minimum value is positive, then all the values of the functions are positive (never reach zero).**Thus if y is never equal to zero the function has no x intercepts**.

The concavity is called by some people the mouth.

The x intercept is where the value of y when graphed lands directly on the x axis. The value of y anywhere on the x axis is zero. The same is true for the y intercept producing an x value of zero. The point at which the graphed line intersects the y axis gives an x value of zero. The value of x anywhere on the y axis is zero.

Carry out the test. The calculator will display a p= value (or if you draw it - it will be the shaded area). This is the type one error. Why? Well if H0 is true then your t-test will come from this distribution. Think of the bell shape as a histogram - you have one value you are comparing to it. Is this value typical of this "histogram"? If the value is near the centre of the bell it is reasonable that it came from it. If it is in the extreme it probably didn't and so we reject H0. The type one error is the probability that we reject H0 given that it is true. H0 assumes the t value comes from this distribution - so it is the probability of getting this value or something more extreme. (i.e. the shaded area. Incidently this is the same way of finding the type one error for any test.
