Assignment #16 Q#s 1‚4‚5 1. Describe the procedure for computing frequencies. Frequencies are commonly used for the initial analysis of a data set. Frequencies provide statistics and graphical displays that are useful for describing all different types of variables. The Frequencies procedure can produce such statistics as: frequencies (counts)‚ percentages‚ cumulative percentages‚ mean‚ median‚ mode‚ sum‚ standard deviation‚ variance‚ range‚ minimum and maximum values‚ standard error of the

1. Following the explosion of the 25th space shuttle flight‚ which was caused by an O-ring failure in one or more of the booster rockets‚ data from the previous 24 flights were studied. The Temperature (F) at the time of launch and whether or not there was evidence of O-ring failures for each of the previous 24 shuttle flights was determined for each flight. A logistic regression relating the Failure of O-rings to the Temperature was obtained with the following result: Estimate Std. Error z value Intercept

I choose statistics as my specialization even though at this time‚ there weren’t many people know about statistics and few students choose statistics as their specialization. I saw in several developed countries such as The Netherlands and Belgium‚ the mathematics degree-holders not only have many opportunities but also were cited
