What is the term for a point that varies greatly from all other data points
xenn [34]

The term for a point that varies greatly from all other data points is known as an <u>OUTLIER</u>

<u></u>

Explanation:

  • An outlier is a data point that differs significantly from other observations. An outlier may be due to variability in the measurement or it may indicate experimental error.
  • An outlier can cause serious problems in statistical analyses.
  • An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst to decide what will be considered abnormal.
  • A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier.
  • The data here appear to come from a linear model with a given slope and variation except for the outlier which appears to have been generated from some other model.
  • Outliers can occur by chance in any distribution, but they often indicate either measurement error or that the population has a heavy-tailed distribution.

Alexus [3.1K]

Answer:

A

Step-by-step explanation:

What divided by 42 equals 14? In other words, you have an unknown number (X), and then if you divide that X by 42 you get 14. Then what is that X? The equation to calculate what divided by 42 equals 14 is as follows: X/42 = 14 Where X is the answer. When we solve the equation by multiplying each side by 42, you get get:

X = 588
