What does the median score mean?
the number that is in the middle of that particular set of numbers.
The three characteristics that describe a set of numerical data are?
mode, mean and median
Which of three three measures of central tendency is most affected by extreme scores?
Of the mean, median and mode the mean would be most affected.
Can you use mean median mode to describe numerical data?
You can use them to describe the central tendency of the data but no more than that.
What is a single number used to describe a set of data mean median mode?
2,5,4,5
What does the median score mean?
the number that is in the middle of that particular set of numbers.
How do you compute for the median class?
The median is the number in the middle. Arrange all the scores from smallest to biggest and the middle on is the median if there is an odd number of scores. If there is an even number of scores, find the mean of the two middle numbers and that is the median.
The mean of 5 different scores is 10 what are the largest and smallest possible values for the median if all test scores must be whole numbers?
If scores of zero are permitted, the lowest median is 2 as in (0,1,2,3,44) and the highest median is 10 as in (8,9,10,11,12). If a zero score is not permitted, then the lowest median is 3 as in (1,2,3,4,40).
Who would use mean median and mode?
I use it in class when looking at my student's scores... Often I look at mean, median, and mode to decide to reteach a concept or not.
What is the difference between the Mean score and the Median score?
mean and median scores. mean is an average of all the scores added together divided by the number of entries. median is the number found in the middle, when catogorized from least or greatest or vice versa. it doesnt matter which way its sorted. the middle number's still the same.
A lopsided distribution of scores in which the mean is much larger than both the mode and median is said to be?
skewed.
When the mean of a distribution of scores of measures is higher than the median the distribution would be?
The distribution is skewed to the right.
Give an example of a set of 6 test scores where the mean and the median have same value but the mode is different?
2, 2, 5, 7, 9, 11. Mean = Median = 6 Mode = 2
What is the statistical difference between a mean and a median?
Mean and median are two of the measures of central tendency. They are numbers that give you information about a group of scores. This is important, because you can't very well go around reciting all the scores of a given sample whenever you need to look at or use the sample. The mean is another term for simple average. You add up all the individual scores, and then divide the sum by the number of scores. If your scores are:1, 2, 3, 6, 8, 14, and 90 then you take their sum, 124, and divide it by 7, the number of scores. You get 17.71, the mean. The mean takes into account the value of every single score. This means that the value of every single score "pulls" the mean toward itself. If any value changes, the mean changes. The median is the score that divides the collection of scores in such a way that half the scores are smaller, and half the scores are larger. Using the same scores above, (they have to be in order) you see that 6, the middle score, divides the group of scores in this way. Three scores are lower, and three are higher. So 6 is the median score. When you have an even number of scores, go half-way between the two middle-most scores. You can see that you could change the actual values of the scores in any number of ways, and still have the same median. This may seem odd, but there may be times when you want your 'estimate' of the population value to be "higher than correct" no more often than it is "lower than correct".
From 11 positive integer scores on a 10-point quiz the mean is 8 the median is 8 and the mode is 7 Find the maximum number of perfect scores possible on this test?
3 perfect scores.
The three characteristics that describe a set of numerical data are?
mode, mean and median
Which of three three measures of central tendency is most affected by extreme scores?
Of the mean, median and mode the mean would be most affected.
