Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Expert Solution & Answer
Check Mark

Answer to Problem 38E

The correct option is “E”.

Explanation of Solution

Given:

If every observation in a data set is multiplied by 10, the only one of the following that is not multiplied by 10 is

  1. The mean
  2. The median
  3. The IQR
  4. The standard deviation
  5. The variance

Calculation:

Measures of center (mean and median) as well as spread (IQR, standarddeviation, variance) are affected by multiplication. However, the variance is multiplied by 100 rather than 10 because standard deviation is the square root of variance.

Hence, the correct option is “E”.

Conclusion:

Hence, the correct option is “E”.
