Finding The Mean Median Mode And Range

The three distinct;calculations associated with the Measure of Central Tendency are the Mean, Median, and Mode. Each measurement is an attempt to capture the essence of how a typical entry or number in the data set may look like. The idea is to compute a single value that can represent the entire elements of the set.

In this lesson, I have prepared eight worked examples to illustrate;how to perform the required computations.

S For The Mean Median And Mode On The Ti 83

Watch the video for the mean and median on the TI 83:

Cant see the video?

Example problem: Find the mean and the median for the height of the top 20 buildings in NYC. the heights, are: 1250, 1200, 1046, 1046, 952, 927, 915, 861, 850, 814, 813, 809, 808, 806, 792, 778, 757, 755, 752, and 750.

Step 1: Enter the above data into a list. Press the STAT button and then press ENTER. Enter the first number , and then press ENTER. Continue entering numbers, pressing the ENTER button after each entry.

Step 2: Press the STAT button.

Step 3: Press the right arrow button to highlight Calc.

Step 4: Press ENTER to choose 1-Var Stats and then type in the list name. For example, to enter L1 press and .

Step 5: Press ENTER again. The calculator will return the mean, x. For this list of data, the TI 83 mean is 884.05 feet .

Step 6: Arrow down until you see Med. This is the TI 83 median; for the above data, the median is 813.05 feet.

Note: The TI-83 plus doesnt have a built in mode function, but once youve entered your list, its pretty easy to spot the mode: its just the number that occurs most often in the set. Not sure? Read more about the mode here.

Thats it!

How Does It Link To Real Life

The Office for National Statistics uses mean to find the mean age of the population. Any role that involves looking at statistical data will likely use all the above measures of central tendency to help draw conclusions from the data.;

People may also use the mode or modal value to estimate how long it takes them to do tasks they do frequently.;

For example, if you timed yourself hoovering where you lived and you had these times in minutes, 10, 10, 8, 13 10. You could say that it takes you around 10 minutes to hoover where you live as 10 is the value with the highest frequency in the data set.

What Does The Term Average Mean

Mean, Median, Mode and Range Foldable Freebie

When people describe the average of a group of numbers, they often refer to the arithmetic mean. This is one out of 3 different types of average, which include median and mode.

Types of Average
The middle number in a set of numbers.
ModeThe number that appears most often in a set of numbers.

In conversational terms, most people just say average whentheyre really referring to the mean. Arithmetic mean and average aresynonymous words which are used interchangeably, according to Dictionary.com.

Its calculated by adding the numbers in a set and dividing it by the total number in the setwhich is what most people do when theyre finding the average. See the example below.

Mean

Set: 8, 12, 9, 7, 13, 10Mean = / 6= 59 / 6The average or arithmetic mean in this example is 9.83.

Median

The median, on the other hand, is another type ofaverage that represents the middle number in an ordered sequence of numbers. Thisworks by ordering a sequence of numbers then determiningthe number which occurs at the middle of the set. See the example below.

Average Median

Set: 22, 26, 29, 33, 39, 40, 42, 47, 53In this example, 39 is the median or middle value in the set.

Mode

The mode is basically the most frequent value thatrepeats itself in a set of values. For instance, if your set has 21, 9, 14, 3,11, 33, 5, 9, 16, 21, 5, 9, what is the mode?

The answer is 9 because this value is repeated 3 times.

Mean Median And Mode Worked Example

Jason

Use the data above to find the mean, median, mode and range of the data.

To find the mean, first add all the data sets.

To solve this we need to add 8, 12, 7, 7 5 and 15. This is 54.

Next we divide by the number of data sets. As this data is for 6 people, the number of data sets is 6. This means I need to divide 54 by 6 or know that 6 x ? = 54. This is 9. The mean is 9.

To find the median I need to re-write the data in order from least to greatest.

5, 7, 7, 8, 12, 15

I then need to find the middle value. As my data set has an even number I need to find the two middle numbers, add them and divide by 2.

My middle numbers are 7 and 8 as there are two numbers either side of them. Adding them up together gives me 15. 15 divided by 2 = 7.5.

To find the mode, I am looking for the data that appears most often. 7 is the only number that appears more than once so my mode is 7.

To find the range, you subtract the lowest value from the data set from the highest. The lowest value is 5 and the highest is 15. 15 5 = 10. The range is 10.;

Alex Timed 21 People In The Sprint Race To The Nearest Second:

59, 65, 61, 62, 53, 55, 60, 70, 64, 56, 58, 58, 62, 62, 68, 65, 56, 59, 68, 61, 67

To find the Mean Alex adds up all the numbers, then divides by how many numbers:

Mean = 59 + 65 + 61 + 62 + 53 + 55 + 60 + 70 + 64 + 56 + 58 + 58 + 62 + 62 + 68 + 65 + 56 + 59 + 68 + 61 + 6721Mean = 61.38095…

To find the Median Alex places the numbers in value order and finds the middle number.

In this case the median is the 11th number:

53, 55, 56, 56, 58, 58, 59, 59, 60, 61, 61, 62, 62, 62, 64, 65, 65, 67, 68, 68, 70

Median = 61;

To find the Mode, or modal value, Alex places the numbers in value order then counts how many of each number. The Mode is the number which appears most often :

53, 55, 56, 56, 58, 58, 59, 59, 60, 61, 61, 62, 62, 62, 64, 65, 65, 67, 68, 68, 70

62 appears three times, more often than the other values, so Mode = 62

Relation Between Mean Median And Mode

SAT Math Part 44 – Data & Statistics – Mean, Median, Mode, Range, & Standard Deviation

The three measures of central values i.e. mean, median, and mode are closely connected by the following relations .

2Mean + Mode = 3Median

For instance, if we are asked to calculate the mean, median, and mode of continuous grouped data, then we can calculate mean and median using the formulas as discussed in the previous sections and then find mode using the empirical relation.

For example, we have data whose mode = 65 and median = 61.6.

Then, we can find the mean using the above mean, median, and mode relation.

2Mean + Mode = 3 Median

Mean = 59.9

Mean Median And Mode Formulas

Pin by Jessica Gold on Math

We covered the formulas and method to find the mean, median, and mode for grouped and ungrouped set of data. Let us summarize and recall them using the list of mean, median, and mode formulas given below,

Mean formula for ungrouped data: Sum of all observations/Number of observations

Mean formula for grouped data: x = \

Median formula for ungrouped data: If n is odd, then use the formula: Median = /2th observation. If n is even, then use the formula: Median = /2

Median formula for grouped data: Median = \

where,

Mode formula for ungrouped data: Mode = Observation with maximum frequency

Mode formula for grouped data: Mode = \

where,

  • l = lower limit of modal class,
  • \ = frequency of modal class,
  • \ = frequency of class preceding modal class,
  • \ = frequency of class succeeding modal class,
  • h = class width
