The range is a measure of the of the smallest and largest values occurring a. sum b. difference c. product 4. The square root of the average of squared differences of each value from the mean is a measure of the dispersion of values of the variable and is called the a. variance b. mean range c. standard deviation 5. In a Gaussian distribution, theare at the center position of the distribution. a. mean b. median c. mode d. all of these 6. The general tendency of values in a series to increase or decrease over time is the series a. cyclicity b. trend c. inclination d. relevance 7. Climate normals are ECV averages calculated from the a nrior.ten.venrs 269 words English (United States)Explanation / Answer
1) D- All of these
Descriptive statistics uses all of these- central tendeancy , dispersion,shape or relative position
2) false
The median of a set of data values is the middle value of the data set when it has been arranged in ascending order. That is, from the smallest value to the highest value.
3- B (difference )
The range is the difference between the largest and smallest data values in the sample. The range represents the interval that contains all the data values.
4) C standard deviation
5) A -Mean
The mean of the distribution determines the location of the center of the gaussian distribution
6) B trend
the general tendency of the values to increase or decrease over time for a series is Trend
9) A - vegetation
Köppen designed the system based on his experience as a botanist, so the main climate groups are based on the different variety of vegetation that grows in climates belonging to each group.
10) B - seed
