2. Based on the scale of measurement for each variable listed below, which measure of central tendency is most appropriate for describing the data?

Statistics provides us with very useful tools and techniques that aide us in dealing with real world scenarios. I have been able to learn several useful concepts by studying statistics that can aide me in making rational and informed decisions that are supported by the analysis results. Statistics as a discipline is the application and development of various processes put in place to gather, interpret, and analyse the information. The quantification of biological, social, and scientific phenomenons, design and analysis of experiments and surveys, and application of

·  How were measures of central tendency used in the study? Did the study use the most appropriate measure of central tendency for the given data? Why or why not?

4. Calculate the following measures of central tendency for the set of cube measurement data. Show your work or explain your procedure for each.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

2. Compute the means for the following set of scores saved as Ch. 2 Data Set 3 using IBM® SPSS® software. Print out a copy of the output. (Please refer to attachment)

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

Sample size for a given confidence level and margin of error (proportions). Poll articles. Hypotheses tests for a mean, and differences in means (independent and paired samples). Sample size and power of a test. Type I and Type II errors. You will be given a table of normal probabilities. You may wish to be familiar with the follow formulae and their application.

The first variable was the number of total prior arrests. The mean was 10.54. The median was 5 and the mode was 0. The most appropriate measure of central tendency for this set of data is the mode. The mode is most appropriate because out of 962 people 290 people had 0 prior arrests. The other numbers of arrests were not even close with the

The best method to solve for the mean, medium, mode, range, variance, and standards deviation, in this case is by hand and not on SSPS. For a novice, they would spend more time figuring how to set the parameters and spend roughly the same amount of time on the analyzation that they would when using the software. Although, a moderate user of the SSPS software would solve this problem rather quickly. Though, it is recommended to use SSPS when analyzing a large sample size.

Indicating the individual number 65 gives a 5 point range to the mean. It seems the median is the most accurate way to discribe the data set, as it uneffected by the outlier value.

“A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data (Laerd Statistics, 2013).” In terms of statistical data, the measurements could be mean, median, and mode. “The mean is equal to the sum of all the values in the data set divided by the number of values in the data set, the median is the middle score for a set of data that has been arranged in order of magnitude, and the mode is the most frequent score in our data set (Laerd Statistics, 2013).” BIMS can benefit from this type of statistical data because the company can get a good picture of the satisfaction

At the bottom of SPSS, there are options to look at the data in Data View or in Variable View. I clicked on Variable View to name my variables. A list of columns appeared, but I only made changes to rows in the Name column. In row 1 under Name, I typed SubjectNo (no spaces or symbols are allowed when naming variables in SPSS) for Subject Number. I clicked back to Data View. The first column was now named SubjectNo, so I typed the list of subject numbers from 1 to 96 (1 number per row) for the number of "participants" in this study. I go back to Variable View and named row 2 as GroupNo. Under the GroupNo column, within Data View, I typed 1’s in rows 1 thru 48 and typed 2’s in rows 49-96. Group 1 was high need for cognition and group 2 was low need for cognition. I labeled the next 45 rows under GroupNO, in the Variable View, as the different item numbers: Item#1 thru Item#45. In all there was a total of 47 rows in the Variable View and 47 columns in the Data View. I clicked back into random.org and highlighted all 4,320 integers not missing any and right clicked for a menu to pop up. In this menu I clicked COPY, then I went back to the SPSS datasheet in the Data View. Under the column labeled Item#1, I clicked on the cell in row 1 and right clicked for the Paste option. All 4,320 integers were placed correctly in the columns, Item#1-Item#45 in 96
