Jacob is not correct. An outlier is a data value that is very different from the other data values that have at least 1 dot. The absence of dots at 1 1/8 inches alone does not automatically make it an outlier; rather, outliers are determined by how they compare to the other values in the dataset. Since the other data points are relatively close in length, 1 1/8 inches may simply be an absent measurement rather than significantly different from the rest.
Mr. Coulson counted the bolts in his hardware cabinet and made a line plot.
A line plot named "Bolt Lengths" shows data from two eighths inches to one and four eighths inches. Three eighths has two dots. Four eighths has four dots. Five eighths has two dots. Six eighths has two dots. Seven eighths has one dot. One has six dots. One and two eighths has five dots. One and three eighths has three dots. One and four eighths has four dots.
Jacob says that 1 1/8
inches is an outlier because it is the only length that does not have any dots. Is Jacob correct? Explain.

Jacob is correct. All of the other data values have dots, so a data value without dots is different and is therefore an outlier.

Jacob is not correct. An outlier can lie anywhere on the line plot, and it must have exactly 1
dot.

Jacob is not correct. The outlier is 1 4/8
inches because the outlier is always the greatest data value.
