Mode, Alpha & Range d. Standard Deviation, Range and Mean e. Median, Range and Normal Distribution B 2 Five numbers are given: (5, 10, 15, 5, 15). Therefore, the median for the given data distribution is 28. Through the single value from the dataset, it reflects the centre of the data distribution. D All of the above. The median is less affected by outliers and skewed data. Moreover, it does not provide information regarding individual data from the dataset, where it gives a summary of the dataset. X bar charts are uses to control the _____ of a process. Along with the variability (dispersion) of a dataset, central tendency is a branch of descriptive statistics.

The purpose of the central tendency is to provide an exact representation of the entire collected data. clint_buringa. Chapter 1: Multiple Choice Questions . A simple measure of dispersion is the range. Solution for A control chart used to monitor a central tendency measure of the process is the Select one: O a. p-chart O b. c-chart O C. x-bar chart O d. Grant… D p-chart. The range is equivalent to the difference between the highest and least data values. Here 12 is the middle or median number that has 6 values above it and 6 values below it. In statistics, the central tendency is the descriptive summary of a data set. Match. Some of the important examples of central tendency include mode, median, arithmetic mean and geometric mean, etc. 1. This activity contains 15 questions. Gravity.

Multiple choice Questions on Total Quality Management. 3 0 obj Since human biases can easily influence the rating process, it is important to create objective measures for rating performance. a) Recruitment b) Employee selection c) Performance appraisal d) Employee orientation Ans: c 0.2. B Range chart. Attention CA - CPC standard Aspirants! It can be calculated as the sum of all the values in the dataset divided by the number of values. We refer to this process as describing the distribution of a variable.
