MxN strategy Here, we specifically use a strategy that selects stocks on the basis of returns over the past M months (i.e. formation period) and holds them for N months (holding period). This is called as the M x N strategy. At the beginning of each month t, the candidate stocks are ranked in descending order on the basis of their returns in the past M months. The top decile portfolio is called the “winners” portfolio and the bottom decile is called the “losers” portfolio. This strategy involves

namely the mean, median and mode, thus giving the readers enough information about the topic and the population being described. For each of the three leading contributor to traumatic brain injury, the article describes the different age groups and the frequency of occurrence of the injury to each group. The mode, i.e. the age group with the highest number of occurrences of traumatic brain injury was identified. Since this data is purely categorical, using the mode to describe the data was indeed

Unit 1 - Fundamentals of Statistics Awilda Luciano American InterContinental University Abstract This report will show how data is analyzed by using measures of central tendency and will include the mean, median, and mode. These are various ways to report averages. In addition will also discuss the ranges of results and how they are dispersed. This is call variance or standard deviation (Bluman, 2010). Introduction Researchers in the United States and around the world are to study

& Sons. Retrieved from ProQuest database What are the characteristics of a population for which a mean/median/mode would be appropriate? Inappropriate The appropriate use of mean, median and mode to determine an average is based on the information gathered. “The mean is the arithmetic average, the median is the point representing the 50th percentile in a distribution, and the mode is the most common score” (Nursing Research, 2011). As the

descriptive statistics, frequency distribution, and histogram. A part of descriptive statistics involves calculating the measures of central tendency and dispersion. Central tendency involves estimates of the mean, mode, and median. The mean can be used in describing central tendency. The mode is the most frequently occurring value in the set of scores (Lind, Marchal, Wathem, 2005). And the median is the score that is found at the exact middle of the set of values. By reviewing and analyzing the central
