Dataset; {0, 1, 2, 3, 32, 33, 34}
In this dataset, median = (n+1)/2th term
= (7 + 1)/2 th term
= 4th term
= 3
When the smallest observation is deleted, dataset is {1, 2, 3, 32, 33, 34}
Median = (6+1)/2th term
= 3.5th term
= (3rd term + 4th term)/2
= (3 + 32)/2
= 17.5
The median have increase multiple folds when the smallest observation was deleted.

The mean in a data set is obtained by: a. calculating the coefficient of variation of the observed values in the data set. b. selecting the value/s in the data set with the highest frequency. c. adding all of the observation values in the data set and dividing the total by the number of observations. d. arranging the observations in ascending or descending order, then selecting the middle value. e. calculating the difference between the largest and smallest values in...

If most of the prices in a large data set are of approximately the same magnitude except for a few observations that are quite a bit larger, how would the mean and median of the data set compare and what shape would a histogram of the data set have? A.The mean would be larger than the median and the histogram would be skewed with a long right tail. B. The mean would be smaller than the median and the histogram...

You have been asked to calculate the Pearson’s correlation coefficients for the variables of a data set. The data set consists of a number of variables and a number of observations of those variables. Discuss how you might improve the computational performance of Pearson’s correlation on this data set if it consists of a) a large number of observations and a small number of variables, and b) a large number of variables and a small number of observations

You are presented with a data-set containing 6 observations, and wish to cluster them using hierarchal clustering. A similarity function s(x,x') is chosen which measures how similar observation r is to observation ', for each pair of observations. The distance function is then defined as d(x, x)-1- s(x,') The similarity scores are give by the below matrix, where the [ijlth entry is the similarty between observations r and a 123456 11.00 0.70 0.65 0.40 0.20 0.05 2 0.70 1.00 0.95...
