Question

enter the answer. use the information to answer the questions. as part of a class activity, students were given a list of 20 words and asked to memorize as many words as they could in 2 minutes. students then had 1 minute to write as many words as they could remember, and the teacher recorded the results as shown. chart with data: 8, 11, 12, 13, 13, 14, 9, 10, 10, 10; 9, 11, 14, 12, 15, 20, 11, 10, 9, 10 suppose the student who remembered 20 words had kept the list and simply copied. if the data point of 20 is removed, what will happen to the shape of the distribution? explain. 1000 words remaining

Explanation:

The data point 20 is an outlier (much larger than most other values like 8 - 15). When an outlier is removed, the distribution becomes more symmetric or less skewed. Initially, with 20, the distribution was right - skewed (tail to the right due to 20). Removing 20 eliminates the long right - tail, making the distribution's shape more balanced, likely approaching a more symmetric or less skewed form (e.g., maybe approximately symmetric around the center of the remaining data).

Answer:

When the data point 20 (an outlier) is removed, the distribution will become less right - skewed (or more symmetric). The outlier 20 created a long right - tail; without it, the data values (mostly between 8 - 15) will have a more balanced spread, reducing the skewness.
