Mean= average =(sum of data values)/(number of data values)

Mode is the most frequent data value.

Median: Sort the data in ascending order. The element in the middle is the median.

If the number of data is odd, there will be one MIDDLE element. It is the median.

If the number of data is even, there will be two elements in the middle. Add the values of these middle elements and divide by 2. The result will be the median. It is not part of the data.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

SOURCE: median for statistics

The TI-30XA doesn't give the median of a sequence of entered values, just the mean, std dev, and other one variable stats

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)

The mean is 10, the median is 9.8, and there is no mode.

You don't need the calculator for that. Sort the data in ascending order.

Mode

Find the most frequent data element (the one repeated the most) in the set. That is the mode. If you have several elements that share the same highest frequency all of them are modes.

Count the number of elements in the set.

If the number of elements is ODD the median is the element that happens to hold the middle place in the ordered set.

If the number of data elements is EVEN, then there is not one middle element, but 2. Call them if you wish MIDLeft, and MIDRight

Take the values of these two elements and calculate their average.

That average is the value of the median.

You can imagine the median as a virtual (not really there) data element inserted between the two middle elements and having as value the average of the two middle elements

Your set would look like the following

{Min_value, ..., MIDLeft_value,

Now, was there something about fractions?

Mean: (60+60+89+90+93+94)/6 = 81

Median: Middle number, in this case between 89 and 90: 89.5

Mode: Most common number: 60

Range: Highest number minus lowest number: 94-60 = 34

Median: Middle number, in this case between 89 and 90: 89.5

Mode: Most common number: 60

Range: Highest number minus lowest number: 94-60 = 34

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

mean: 77

median: 87

mode: none or all of them (take your choice)

range: 43

If this is homework, be sure to show your work.

The mean of a distribution is represented as an x with a bar above it. (xbar). When you scroll along the statistics you will see the Median, Xmax, Xmin, Q1, Q3, n. All clearly identified. Maybe you should learn mor about the theory.
