Column Mean Standard error Median Mode Standard Deviation Sample variance Kurtosis Skewness Range Minimum Maximum Sum Count Largest(1) Smallest(1)
Directions: Calculate the mean, median, mode, range, variance, and standard deviation (SD) for each set of data. Please show your work on a separate sheet of paper and submit it along with this worksheet. Make sure your name is on the separate sheet. All answers must be written on this sheet. 1. Data Set: 1, 3, 1, 5, 7, 2, 4, 1, 3, 6, 2, 5, 2, 6, 8, 8, 2, 1, and 3 Mean = _____ Median=_____ Mode=_____ ...
Find the sample mean, the median, the mode, the variance, and
the standard deviation.
An insurance company experienced the following mobile home losses in 10,000's of dollars for 50 catastrophic events: 5 6 77999 10 12 22 24 28 29 31 33 36 38 38 38 39 4 48 49 53 55 74 82 117 134 192 207 224 225 236 280 301 308 351 527
A random sample of n=7 observations are drawn from a normal population with mean and variance σ^2. The mean and variance of the sample are 1.45 and 2.07 respectively. Calculate a 90% confidence interval for the population standard deviation.
Find the sample mean, sample median, sample standard deviation, and sample variance of Tthese numbers. 2. A discrete RV has a pdf of the form: P(x) C2, 0,1,2,3. a) What is C? b) What is P(X> 2)? b) What is P(X 2 2)?
4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...
1. A student was asked to compute the mean and standard deviation for the following sample of n= 5 scores: 81, 87, 89, 86, and 87. To simplify the arithmetic, the student first subtracted 80 points from each score to obtain a new sample consisting of 1,7,9,6, and 7. The mean and standard deviation for the new sample are then calculated to be M=6 and s = 3. What are the values of the mean and standard deviation for the...
