Q. Select the outlier in the data set.6,74,80,82,84,91,93,94
Identify data set: Identify the data set and understand what an outlier is.An outlier is a data point that is significantly different from the rest of the data. In this case, the data set is 6,74,80,82,84,91,93,94. To find the outlier, we can look for a number that seems unusually low or high compared to the others.
Observe data set: Observe the data set to see if any number stands out.By looking at the data set, we can see that the number 6 is much lower than all the other numbers, which are all 74 or higher. This suggests that 6 might be the outlier.
Calculate statistics: Calculate the range, mean, and standard deviation if necessary.To confirm that 6 is an outlier, we could calculate the mean and standard deviation and then determine if 6 falls far outside the range of what would be expected. However, in this case, since 6 is so clearly different from the other numbers, we can conclude it is the outlier without further calculations.
