Q. Select the outlier in the data set.3,69,73,77,78,81,89,91,93
Identify data set: Identify the data set and understand what an outlier is.An outlier is a value in a data set that is significantly different from the other values. It is an extreme value that stands out from the rest of the data.Data set: 3,69,73,77,78,81,89,91,93
Look for outlier: Look for the value that seems significantly different from the rest of the data. By inspecting the data set, we can see that the number 3 is much smaller than all the other numbers, which are all close to each other and within the range of 69 to 93.
Determine suspected outlier: Determine if the suspected outlier is indeed an outlier by comparing it to the rest of the data.The number 3 is much lower than the next smallest number in the set, which is 69. This large gap suggests that 3 is an outlier.
Conclude outlier: Conclude which number is the outlier.Based on the significant difference in value, we can conclude that the number 3 is the outlier in the data set.
