Explanation Given: The average number of times that people change jobs during their careers. The three most common measures of Central tendency are Mean, Median and Mode. Mean: The mean or average is equal to sum of all values in the data set divided by the number of values in the data set. Mean is best measure of central tendency with continuous data and it is also used with discrete data sometimes. Since mean is affected by outliers, it is the best measure of central tendency when the data is symmetrical. For Example: calculating mean for the following two data sets. 1) 1,2,4,6,8,6,4,3,2 T h e m e a n i s = S u m o f a l l v a l u e s N u m b e r o f v a l u e s = 36 9 = 4 2) 1,2,5,8,10,8,6,3,100 t h e m e a n = S u m o f a l l v a l u e s N u m b e r o f v a l u e s = 143 9 = 15.89 If we observe here because of 100 in the second data set the mean is very high when compared to all data points in the data set...

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

7.2.10 Researchers in the Hopkins Forest also count the number of maple trees (genus acer) in plots throughout the forest. The following is a histogram of the number of live maples in 1002 plots sampled over the past 20 years. The average number of maples per plot was 19.86 trees with a standard deviation of 23.65 trees. a. If we took the mean of a sample of eight plots, what would be the standard error of the mean? b. Using the central limit theorem, what is the probability that the mean of the eight would be within 1 standard error of the mean? c. Why might you think that the probability that you calculated in (b) might not be very accurate? 2. A normal population has mean 100 and variance 25. How large must the random sample be if you want the standard error of the sample average to be 1.5?

Answer questions 7.3.10 and 7.3.12 respectively 7.3.12. Suppose that two independent random samples (of size n1 and n2) from two normal distributions are available. Explain how you would estimate the standard error of the difference in sample means X1 − X2 with the bootstrap method.
