Consider the following data set:
3 -5 5 7 9 10 -3 35 2 1 1
a) Determine by hand (you can use the calculator) the mean,
median and mode of this data set. show enough details in your work
for it to be clear that you did this work.
b) Use MINITAB to obtain the above results for this data set
(and only these results).
c) By hand clearly determine the 5 number summary for this data
set and...

Above we have the final averages of the last stats and I want to
know if the class average falls within the boundaries of all my
statistics classes for the past 20 years.
Find the sample size, mean, and standard deviation of the data
above (Table 1)....
For the following data set, X: 9, 6, 8, 3, 8, 9, 3, 4, 3, 7:
Calculate:
1. Variance
2. Mode
3. Mean
4. Mean Average Deviation (MAD) about the mean
5. Median
Use this sample data set to answer the next question
2, 3, 5, 7, 9, 10, 14, 15, 16
From this data:
Find the mean, median, and mode(s) if any exist.
Find the variance and standard deviation of this
sample
Find the values of Q1, Q2, Q3 and the IQR
3, 7, 8, 5, 6, 4, 9, 10, 7, 8, 6, 5 Using the previous question
's scores, If three points were added to every score in this
distribution, what would be the new mean? If three points were
added to every score in this distribution, what would be the new
standard deviation. Remember, you have already calculated
population standard deviation in a previous problem. This problem
requires two answers.

1. For the given data set representing the runs scored by two
players in last 15 matches, conduct the following analysis:
i. Which average you will use to summarize...
The following is a sample of 20 measurements.
10 7 6 12 11 9 8 13 11 11 12 6 8 7 15 9 12 6 10 10
Compute the Sample mean (x), Sample variance (s2 ),
and the Sample standard deviation (s).
(round to two decimal places)
Count the number of measurements in the intervals
x ±s, x ±2s, x ±3s.
Express each count as a percentage of the total number of
measurements.
