Answer:

  • Standard deviation
  • Range

Step-by-step explanation:

Two identical sets of data are:

  • Data Set 1: 58, 59, 62, 64, 67, 67
  • Data Set 2: 58, 59, 62, 64, 67, 67

An outlier is added to Data Set 2. This is the number that is either smaller than 58 or greater than 67.

Mean

  • No, it could be greater or smaller

Standard deviation

  • Yes, it will increase with an outlier added because the difference between the added number and the mean will be the greatest.

Mode

  • No, it could be greater or smaller

Median

  • No, it could be greater or smaller

Range

  • Yes, it will increase as either lower or the higher value will be added to the data set.
