Posted by Jon on Wednesday, March 5, 2008 at 6:36pm.

For questions 1 and 2 use the following info. The numbers are in this order: 456,306,160,363,376,935,54,349

1)Find the mean, median ,mode, and standard deviation of the data. Round to the nearest hundredth, if nessesary.

mean= added all numbers and divided by 8 and got 384.9

median= subtracted largest number and smallest number and got 881

mode= clustered values such as 306,363,376,349 so the mode is 300

standard deviation= I had to find the variance first which is 59476.6 and I took the sqrt of that and got 243.9



2)Determine whether the data in the table appears to be positively skewed, negatively skewed, or normally distributed. Explain.

Normally distributed but I can't explain.
