Table 1: Sorted Summary Statistics Mean-2σ 0.8 Minimum 2.0 Q1 4.0 Mode 4.0 Median 6.0 Mean () 6.1 Q3 8.0 Mean+2σ 11.3 Maximum 15.0 After analyzing the tropical cyclone data I determined the mean, mode, and median in order to identify the various measures of center. As shown in Table 1, the most frequent number of hurricanes per year was 4 and is defined as the mode. The median and mean were very close at 6.0 and 6.1.; which indicates that there was an average

QUANTITATIVE METHODS AND ANALYSIS Fundamentals of Statistics Raymond Lawson AIU Online Virtual Campus Abstract This paper will discuss the analysis of two sets of data. The mean, median, and mode will be analyzed and charted. The standard deviation will also be discussed along with the variance. A summary of the data and its results will be discussed in conclusion. Fundamentals of Statistics Statistics are used for many different things in our lives. We have used them to in order to

ordinal scales cannot be assumed, they are only ranked or rated on a relative scale. Ordinal scales are usually non-numeric thoughts like satisfaction, happiness or discomfort. You can determine central tendency on a set of ordinal data using mode or median. Interval level of measurement is the next level and can be described as measurement based on a scale with a known unit of measurement. In interval measurement we are able to determine the order as well as the exact difference between the

When calculating the central tendency, you have to calculate the mean, which is the most common measure of central tendency, acts as a balance point, and is affected by extreme values (outliers). The mean is calculated by taking raw data (a group of numbers), adding them up for a total, and then dividing that total by amount of numbers within the group ( ex: raw data: 3,4,5. 3+4+5=12, then 12/3= 4. The mean equals four). The median, which is the middle value in ordered sequence (If this value is

Central Tendency, the Mean Perhaps the most well-known statistical tool is the mean, the arithmetical average of numbers. Add the seven numbers 100, 100, 90, 80, 70, 60 and 50, and you get a sum of 550. Divide 550 by 7, and the result is 78.571428. This is the mean average of the numbers. The result can be rounded off to 78 or 79, for the purpose of the statistics. Central Tendency, the Median The median is the middle number in a group. Consider the seven numbers 100, 100, 90, 80, 70, 60
