Can you answer the following questions?
Open up a python shell or notebook and play with these ideas a bit.
Try this out:
scores = [85, 90, 78, 92, 88, 95, 80, 87, 94, 89]
# Calculate measures of dispersion
range_score = max(scores) - min(scores)
variance_score = statistics.variance(scores)
std_dev_score = statistics.stdev(scores)
# Display measures of dispersion
print(f"Range of Scores: {range_score}")
print(f"Variance of Scores: {variance_score}")
print(f"Standard Deviation of Scores: {std_dev_score}")
For this code to function, you must import the statistics package. Can you recall how to do this?
