Step 1:Find “r”, the common ratio. Each number is multiplied by 2 in this sequence (8 / 4 = 2), so r = 2. There’s no need to go any further: 2 is not between -1 and 1, so this sequence doesn’t have a sum.
We’ve discussed pooled standard deviations at length, but what other tools might benefit your analysis? You’re likely going to be looking atCpk and Sigma Levelwhen viewing your production line. As such, understanding how they inter-relate and differ is key. ...
How to Complete an Excel ANOVA The difficulty of calculating ANOVAs by hand prevented most people from using this Six Sigma tool until the 1990s. Now, using software like Microsoft Excel, anyone and everyone can quickly determine whether differences in a set of counts or measurements were most ...
Interdisciplinarity is a polysemous concept with multiple, reasoned and intuitive, interpretations across scholars and policy-makers. Historically, quantifying the interdisciplinarity of research has been challenging due to the variety of methods used to identify metadata, taxonomies, and mathematical formulas...
Understanding the drivers of economy-wide productivity growth has long been of interest to academics and policy makers. In this paper, we contribute to the

The grade point average (GPA) usually averages all these data points to better understand a student's overall academic performance. Descriptive statistics help summarize data meaningfully, allowing us to find patterns that emerge from it. So, the GPA is an excellent example of descriptive statistics...
Sums can be written using the Greek capital sigma ∑ notation to compactly denote repeated addition. ∑ provides a shorthand for writing out sequences of numbers being added together. What is the sum of squares? The sum of squares is the result obtained when you take a set of numbers, squ...
Variance:The variance of a random variable is the averaged squared deviations of data from the mean. The variance is often denoted by {eq}\sigma^2 {/eq}, where {eq}\sigma {/eq} is the standard deviation. We will use these steps and definitions to calculate the variance of the...
After major negative news, managers may actively disclosure more informative information in their MD&A sections to build investor confidence and mitigate negative effects such as stock price volatility. 3.2. Management confusion The IRH asserts that when extracting statistics from public data becomes too ...
