Tendency formula
Web8 Dec 2024 · The central tendency tells you where the middle of the data is, or the average value. Some standard measures of the central tendency include the mean, the median, and the mode. The spread of data means how much individual results differ from the average. WebThe mean is equal to the sum of all the values in the data set divided by the number of values in the data set. So, if we have n values in a data set and they have values x 1, x 2, …, x n, the sample mean, usually denoted by x ― (pronounced "x bar"), is: x ― = x 1 + x 2 + ⋯ + …

WebThe next step is decided by whether the value of N is even or odd. If the value of N is odd then simply the value of (N+1)/2 th item is median for the data. If the value of N is even, then use this formula: Median = [ size of (N+1)/2 term + size of (N/2 + 1)th term]÷2. WebDulong's Formula. The heating value of a fuel can be calculated with the results of ultimate analysis of fuel. From analysis, percentages of the combustibles in the fuel (carbon, hydrogen, sulfur) are known. Since the heat of combustion of these elements is known, the heating value can be calculated using Dulong's Formula:
