QuestionIf all the numbers in a set appear once, how do I find the mode?DonaganTop AnswererAs the article points out, the set is "multi-modal" and thus doesn't have a single mode.
-
QuestionWhat does modal mean?Community AnswerModal is just the adjective form of the word mode. So, the modal value in a data set is the same as the mode.
-
QuestionHow do I calculate the mode in the following dataset? 1, 2, 3, 4, 1, 2, 1, 2, 1, 2Community AnswerStart by lining up the data in ascending order, so it's organized in an easily readable fashion: 1, 1, 1, 1, 2, 2, 2, 2, 3, 4. Then, figure out which number appears most often. This is the mode. In your dataset, there are actually two modes -- 1 and 2. They both appear 4 times and nothing else appears more.

QuestionWhat is the mean with the numbers 72, 52, 80, 88 and 100?Community AnswerYou can find the mean by adding all of the numbers in the data table together, and then dividing them by the number of numbers you added together. In this case, 72+52+80+88+100=392. After adding them together, you would divide by 5, because you added 5 numbers together. The final answer is 78.4.
-
QuestionIf I have three fours and three fives, what is the mode?Community AnswerIf there is no other number that shows up more than three times in your data set, then you have two modes, 3 and 4. This type of data set is called bimodal.
-
QuestionIf there is more than three numbers, how to solve it?Community AnswerAdd all the numbers together, then divide by the number of the numbers that you added together for the mean. For example, if you needed to solve the mean of v, x, y, and z, then you would add v+x+y+z then divide by 4, as you added 4 numbers together.

QuestionHow do I calculate the median of -1, 2, 3, 4, 2, 5, 3, 6, 5?DonaganTop AnswererPlace those numbers in ascending (or descending) order: -1, 2, 2, 3, 3, 4, 5, 5, 6. There are nine numbers in the set, so eliminate the first four numbers and the last four numbers, leaving the ninth (or middle) number, which is the second 3. That's the median.
-
QuestionDoes the median change if the numbers are ordered from greatest to least?Community AnswerNo, but you should learn to order them from least to greatest because it will make it easier when you do more complicated things, such as finding the first and third quartiles of the data.
-
QuestionWhat is a multimodal distribution?ChristopherTop AnswererIf a distribution is termed to be multimodal, there are at least two modes in the distribution. This means that at least two numbers appear the greatest amount of times in the distribution. For example, if you have a set of data in which three numbers each appear five times and no other numbers appear more than five times, then you have a multimodal distribution with three modes.
-
QuestionIf there aren't any recurring numbers, how do I find the mode?DonaganTop AnswererIf each number in the set appears the same number of times (such as once), the set is multi-modal, and every number is the mode. You could also consider this set non-modal, having no mode at all.
-
QuestionHow do I present information that is bimodal?DonaganTop Answerer"Bimodal" means that the modal number appears twice in the set. Present the set as you would any other set.
-
Question80,85,90,95,100,105,110,115,120,120,125,130. What is the mode?Community AnswerRemember that the mode is the most common number within the data. In this list, only one number appears more than once. Therefore, the mode of this data is 120.
-
QuestionHow do I find the first and third quartile of data in a set?Community AnswerTake the data, plot onto a graph and divide the total results by 4. Those numbers that appear within the first quarter of all the data on the graph would be within the first quartile, and the third quartile would be the data that occurs from the mean of the results up to the last quarter of the data present.
-
QuestionIf I am working on a median, can I repeat the same number?Community AnswerThe median will include repeats. For the three main statistical values, mean, median, and mode, you will never omit any numbers.
-
QuestionHow do I calculate the range with a large group of numbers?Community AnswerIf it is a large group of numbers, find the lowest number and the highest number. That is the range.

QuestionWhat are the median and the mode of 21, 16, 24, 7, 19, 16, and 11?I_l1ke_gam3sCommunity AnswerFirst arrange the numbers in either ascending or descending order: 7, 11, 16, 16, 19, 21, 24. The median is the number positioned in the middle of the grouping. Since there are seven numbers in the grouping, the fourth number is in the middle. So the median is 16. The mode is the number that appears most frequently in the data set, which in this case is also 16.
-
QuestionWhat is the median of 2, 3, 4, 5, 6, 8, 8, and 8?Community AnswerThe numbers are already arranged in ascending order. There are eight numbers in the group. When there is an even number of numbers in the group, there are two middle numbers. In this case, the middle (median) of the group consists of the average of the fourth and fifth numbers: (5 + 6) / 2 = 11/2 = 5½. That's the median.
-
QuestionIf there is no repeated value in a data set, how do I find the mode?I_l1ke_gam3sCommunity AnswerThere is no mode. If every number in a data set appears once, there is no mode.
-
QuestionHow do you find the median in the following data: 2, 8, 5, 9, 7, 1?Community AnswerFirst list the numbers in either ascending or descending order: 1, 2, 5, 7, 8, 9. Because there is an even number of numbers (6) in the data set, the median will be the average of the middle two numbers (which you find by adding those two numbers together and dividing by 2): (5 + 7) / 2 = 6. That's the median. (It's only a coincidence that the median in this case is the same as the number of numbers in the set.) (If there had been an odd number of numbers in the set, the median would have been the middle number.)
-
QuestionHow do I calculate the mean: 1, 2, 2, 2, 4, 6, 2?Community AnswerAdd up all the data then divide by how many there are. When you add up all the data, you'll receive an answer of 19, But then dividing by 7 will give you 19/7 or 2 5/7.
-
Questionwhat is the median of 23, 24, 25, 26, 27, 28, 29, 30I_l1ke_gam3sCommunity AnswerThe median is the middle number of this data set. The median is 26.5 because it is between 26 and 27.
-
QuestionWhat is the mode for 23, 24, 25, 26, 27, 28, 29, 30?Community AnswerThis data is called non-modal, because there is no mode, and everything is listed only once.
-
QuestionWhat are the mean and median of the following numbers: 9.4, 9.5, 4.3, 10.6, 7.6, 17.8 and 7.0?I_l1ke_gam3sCommunity AnswerThe mean is the sum of the numbers divided by the number of numbers. The median is the middle number when all the numbers are arranged in either descending or ascending order. (If there are two middle numbers, the median is the average of those two numbers.)
-
QuestionCan I use a decimal as the mean?Community AnswerYes. The mean does not have to be a whole number.
-
QuestionWhat is the mean of this data: 2, 206, 80, 508, 69?Community Answer(2 + 206 + 80 + 508 + 69) / 5 = 865 / 5 = 173.
-
QuestionWhat is the median of 2, 3, 4 and 4?I_l1ke_gam3sCommunity AnswerIt's 3.5. Since there are two middle numbers (3 and 4), the median is the average (mean) of them. 3 + 4 = 7. 7/2 = 3.5.
-
QuestionWhat if while calculating the median of a set with an even amount of numbers, the value you get that has to be divided by 2 is odd? How do you solve it then?Community AnswerThe median won't be a whole number, which is okay. When you divide an odd number by 2, you'll get a number like 3.5 or 3½.
