What is the median of 15 min57sec and16min1sec?
The median of an even number of data points is the mean of the two that are central. Since you gave only 2 data points, the median is going to be the mean of the two data points, so 15'59" ■
How do you work out speed using mean and median?
Mean is the average of a set of data points = (Sum of all data) / Quantity of DataMedian is the middle of a set of data points = Data whose index is the integer nearest ((Number of Data+1) / 2)Example Data:2, 3, 5, 3, 2The mean = (2+3+5+3+2)/5 = 15/5 = 3The median = Index((5+1)/2) = Index(6/2) = Index(3). The third item on our list is 5.
If a set of data has 100 points and variance 4 then the standard deviation is?
The SD is 2.
Can you have more than one outlier?
Yes, a data set can have more than one outlier. An outlier is a data point that significantly differs from the rest of the data. The presence of multiple outliers can impact the overall distribution and analysis of the data.
What if the median equals the minimum value?
The only way that this could happen if enough of the data points have the same value at the minimum. The median is the middle number in a set of data points.So for example: {2,2,2,3,4}. The middle number is 2, which is also the minimum value.
How many data points are needed to identify a statistical trend?
1. 6 or more consecutive points increasing or decreasing 2. 8 or more consecutive points on one side of the center line 3. 4 out of 5 points beyond 1 sigma 4. 2 out of 3 points beyond 2 sigma 5. Any (1) point outside the control limits
How do you get slope with no graph?
If you are given 2 data points, you can do (y1-y2)/(x1-x2) with the points. Given two intercepts, you can assume points based on the intercepts (if the x-intercept is 7, then one data point is (7,0). Then you can do the above once you do the same for the y-intercept.
What is the most reasonable data for 2 4 1 7 5?
All five points are reasonable.
What is the TRIMMEAN function for in Excel?
TRIMMEAN calculates the mean taken by excluding a percentage of data points from the top and bottom ends of a data set. You can use this function when you wish to exclude outlying data from your analysis. =TRIMMEAN(array, percent) Array is the array or range of values to trim and average. Percent is the fractional number of data points to exclude from the calculation. For example, if percent = 0.2, 4 points are trimmed from a data set of 20 points (20 x 0.2): 2 from the top and 2 from the bottom of the set. It does not matter what order your values are entered in. It will remove some of the highest and some of the lowest.
What data can have only 2 values?
A binary variable.
In a coordinate graph of two related variables when does it make sense to connect the points?
When the data on the graph is continuous,it does make sense to connect the points on the graph of 2 related variables.
Find common points of earthquakes and volcanoes?
there are only 2
