What is the median if the scores of an even number of cases are arranged from high to low?

If it is a small list of scores, like 6 of them, write them in a list, for example:
96, 87, 80, 79, 75, 75
Find the 'middle' which will occur BETWEEN two numbers
96, 87, 80 (middle) 79, 75, 75.
Average the two numbers on either side of the 'middle.' In this example (80 + 79) / 2 = 79.5
If the list is larger find the middle by dividing the total number of cases by 2. In this example 6 / 2 = 3. The median will be the middle BETWEEN the 3rd and 4th score. (Average the 3rd and 4th score)

Does the median have 50 percent of the cases below only in a normal distribution?
No. By definition of the median, the median has 50 percent of the case below and 50 percent of the cases above. This has nothing to do with the cases being in a normal distribution.
When is mode the best of measure of central tendency?
never * * * * * When the data are qualitative. The mean and median are unusable in such cases and the mode is the only sensible measure.
How do you know which measure of central tendency best describes the data?
The answer will depend on the nature of the data.If the data are qualitative then the only option is the mode.If they are ordinal then you have a choice between the mode and median. The mode may be a better measure when the data are very skewed. Otherwise the median is usually better.For any higher level of measurement is is also possible to calculate the mean. In such cases the median or mean are better. For very skew distributions the median is better but otherwise is should be the mean.
What is the answer of the median if it is between 8 and 8?
well if by between 8 and 8 you mean 8+8 then divide it by two to get......8.- Yep, you are absolutely right!! if there were 3 numbers in a data set then u would have to cross keep crossing out numbers from each side until you get a remainder of only one number. In some cases you will not get ONLY one number. So, you would have to:1) Add 8 + 82) You get 16. So divide 16 by two because there are only two numbers in the set.3) You get 8.4) The median of 8 and 8 is 8!
What is the formula of prevalence?
True Cases divided by the total Number in the population.
Does the median have 50 percent of the cases below only in a normal distribution?
No. By definition of the median, the median has 50 percent of the case below and 50 percent of the cases above. This has nothing to do with the cases being in a normal distribution.
Mode always contain the median?
No. Mode and median are two different descriptive statistics. The mode is the value that occurs most often. The median is the middle value (the value below which 50 % of the cases lie and above which 50 % of the cases lie). Here is an example. Consider the set of data. 2,3,3,5,5,5,6,8,10 3 occurs most often (3 times), so 3 is the mode. 5 is the median. There are 4 cases below 5 and 4 cases above 5.
What is the median of 97 85 92 and 86?
The idea is to sort the numbers, and pick the number in the middle as the median. In cases like this, when you have two numbers in the middle (the size of the set is even), take the average of those two numbers.
What are the median prices for computer cases?
Prices start at around 50$ and go up as high as you like.In general 80$ seems like the median price.
Median of ungrouped data?
Arrange the values in increasing order. If the number of observations n is odd, the median is n/2+1 st value. n/2 is integer division (ignore the fraction). If there are 5 observations, the median is 5/2+1 = the third observation. If the number of observations is even, median = [ x(n/2)+x(n/2+1)] /2, the average of the two middle values. If there are 10 observations, 10/2 +(10/2+1), the average of the fifth and the sixth observation. The median is such that 50 % of the cases lie below it and 50 % above.
What are the minimum scores for SAT for student athletes entering college?
Minimum SAT scores will be particular to the institution requiring them, and may in some cases be department specific.
What is an advantage to using the median when examining a set of data?
The median or mode should be used instead of the mean in distributions with extreme outliers. In such cases, the mean can be a misleading measure of central tendency and the median value or the mode value are typically more accurate measures.
Does a median divide a triangle into two congruent triangles?
Yes * * * * * No. A median is a line from a vertex to the midpoint of the opposite side. It divides the triangle into congruent parts only if the triangle is equilateral or if the triangle is isosceles and it is the median from the unequal vertex. In all other cases the two parts will not be congruent.
How do find median of a set of numbers?
you like cross 1 number out on each side until you have one nuber left i think in some cases but im not like 100 percent sure about the two number thing i just know that you cross it out out until you get to the middle
How do you calculate an interquartile range with an even number of scores?
If you have 2n scores, then Q1 = (2n+1)/4 Q3 = 3*Q1 In both cases, depending on your level, you take the nearest integer to Q1 and Q3, or you interpolate. If you do not know what interpolate means then you are probably not yet at the necessary level! and IQR = Q3 - Q1
What results can be expected from a gastroduodenostomy?
good to excellent gastroduodenostomy results are reported in 85% of cases of gastric obstruction. In cases of cancer, a median survival time of 72 days has been reported
What is the formula of simple percentage in statistical treatment in research?
There are two formulas used in getting the simple percentage in statistical treatment in research. The first formula, Frequency and percentage distribution, % = f/N x 100, where f is the frequency and N is the number of cases. The next formula is Mean where the mean equals the sum of all scores divided by the number of cases.
