Is it true that the median is always one of the data points in a set of data?

No. If there is an even amount of numbers and the two middle numbers are different, then it is the number that is halfway between them, which obviously means it is not in the data set.

No, it is not necessarily true that the median is always one of the data points in a set of data. The median is found by arranging the data in numerical order and selecting the middle value. This value might be one of the data points, but it could also be the average of two data points if there is an even number of values in the set.

Is it true that two points are always collinear?
Yes, two points are always collinear. You can draw a line through any two points.
Is it true that all data points have to be shown?
The answer depends on the purpose of the plot.
Three points are always coplanar?
YES!
Is it true that three points are always contained in exactly one plane?
3 points must always be contained in one plane, as 2 make a line, it makes no difference as to where the third point is, it will exist in the same plane in the two. Aside from all three points being in a line, this is always true.
What does mean median mode means?
Mean is an average of a list of numbers. Median is the middle of a list of numbers. Mode is the most common number in a list of numbers. Ex. 14 17 23 48 54, the Median would be 23, the mean would be 31.2, and the mode would be undefined. The mean, median, and mode are all measures of center for a data set. A measure of center is one way to get a single result that represents all of your data for a definitive answer to a math or science question. Mode is the number that shows up most in the data set. Mean (also known as average) is found after all the numbers in a data set are added together, and that sum is divided by how many numbers in the data set there are. Median is the number in the exact middle of the data set once the data set is put in the order of least to greatest value. If the number of numbers in the data set is even, and there are two medians, then you would find the mean of the median to get your true median. Here is an example. data set: 0,0,3, 4, 5,5,5, 66, 78, 80, 90, 99,99,99,99, 106 mode:99 median: 72 mean:48
Which measures of central location always have only one value for a set of grouped or ungrouped data?
Mean and median are the measures of central location that always have one value. This is true for a set of grouped or ungrouped data.
Are collinear points always coplanar?
true
Is it true that two points are always collinear?
Yes, two points are always collinear. You can draw a line through any two points.
Is it true that all data points have to be shown?
The answer depends on the purpose of the plot.
Do points plotted on a line graph represent the actual data recorded by an experiment?
Yes, it shows the data in a different way
Three points are always coplanar?
YES!
Does Data always contains facts true or false?
Data always contains information, but not necessarily facts. Data can be completely made up.
If the coefficient of determination for a data set containing 12 points is 0.5 6 of the data points must lie on the regression line for the data set.?
That is not true. It is possible for a data set to have a coefficient of determination to be 0.5 and none of the points to lies on the regression line.
Is the best-fit line helpful in estimating vaules of data points true or false?
Yes. (True)
Is it true that the score of the same data with the same mean are always the same?
No, it is not true.
If three points are coplanar are they also collinear?
Is false
The best fit line is helpful in estimating values of data points?
True
