The correct answer:
A unique kind of average is an index number.
Explanation:
The same unit is used in an absolute measure of dispersion as it is in the original data set. The absolute dispersion approach describes fluctuations as the mean of observations' standard or mean deviations. Range, standard deviation, quartile deviation, etc. are included.
The correct answer:
54
Explanation:
The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.
Explanation:
First or lower quartile is another name for the 25th percentile. The value at which 25% of the answers fall below it and 75% of the responses fall above it is known as the 25th percentile. The median is another name for the 50% percentile. The data set is divided in half by the median.
The correct answer:
Range
Explanation:
"The statistical metric that identifies a single value as representative of an entire distribution" is the definition of central tendency. [2] It strives to give a precise account of all the facts. It is the lone value that best typifies or reflects the information gathered.
Explanation:
The statistical concept of dispersion, which can be quantified by a number of different statistics including range, variance, and standard deviation, refers to the size of the distribution of values anticipated for a given variable.
The correct answer:
17
Explanation:
A dataset listed in ascending order is given a median value using a statistical technique.
Explanation:
The sum of the standard deviations is 0. The total of the deviations below the mean will always equal the sum of the deviations above the mean because this is a characteristic of the sample mean.
