Please see my other Web Development articles. OOP: Encapsulation, Inheritance, Polymorphism, Composition Object-oriented Programming (OOP) provides the most feature-rich, maintainable, feature-rich way of programming applications by levering the following features. (use table to link to each article listed above). Please see my other Web articles. Object-Oriented Programming Abstract Classes vs Interfaces Class Design – Step…
Please see my other Web Development articles. Using Object-oriented Programming (OOP) to Design Robust Classes At the beginning of a software project, beginning by documenting in story-like form, the purpose for the project or what business problem are users trying to solve. List all users of the system and for each, what actions they require…
Probability: Independent and Dependent In my Probability article, I demonstrated determining the likelihood of events related to students and their grades using a single event. In this article, I will demonstrate the nature of events used in probability determination – either they are independent or dependent events. Independent Events Returning to the example from the…
Determine the Likelihood of an Event Similar to my Distribution articles, Probability is another concept which focuses on how likely an event will occur. Single Event Probability The following formula returns the likelihood of an event using how many events qualify for the desired outcome (criteria), divided by the total number of possibilities. To illustrate…
Understanding Distribution Shapes and Central Tendency In many of my BI articles I discuss data and its measurements, one of the most commonly used being the mean (link) or average of all values within a data set. A data set contains many data points, their arrangement around the mean and their probably of occurrence is…
Ensuring Tables Intuitively Communicate Data During most data analysis, team members must review many small to large data sets. Often, these data sets resides within poorly designed tables, wasting much time when they should have first re-designed those tables to make the data more intuitive and easier to discern patterns. In this article, I will…
Please see my other Statistics articles. Choosing the Correct Method to Intuitively Communicate Data Patterns. Many options exist to intuitively communicate patterns in data for enable strategic decision-making. The following table recommends charts depending on your goals. Chart Purpose Example Bar, Pie Charts Simplest method for summarizing data. Note: Use a pie chart or horizontal…
Please see me my other Excel articles. Understanding Data Set Extremes Understanding the lower and upper limits of a data set may be the first and most necessary place to begin during any analysis. In this article, I will begin the same data set from my Chart – Bar article – disease diagnoses by age…
Please see me my other Excel articles. XY Scatter Plot: Comparing Data Correlations Unlike other charts where data points form a contiguous shape whether in bars (bar chart) or slices (pie chart), scatter plot charts display distributions with individual data points, reflecting correlations between values. The name of this type of type begins with “XY”…
Please see me my other Excel articles. Quickly Communicating Data Points While many charts communicate data trends effectively, they do not do show them efficiently. In other words, if the user only requires a quick snap shot of the data, a verbose, heavy-graphic chart wastes valuable time on the part of the user when only…
