Strategic Vision Relationship Map
This is a relationship map for my strategic vision for 2024-2027
Organizations That Do Not Use Basic Rigger
This report is an overall analysis to identify any organizations that do not use Basic Rigger. This identification would allow us to pinpoint possible customers to reach out to for market information
Embeddings for Item Development
The purpose of this prototype demonstration is to present how items can be constructed and analyzed without response data. This demonstration uses item embeddings to examine similarities between items with respect to the words contained in the item stems.
Mobile Crane Usage: Assessments and Practical Exams
This report provides an analysis of the usage of NCCER's Mobile Crane Operator Certification Program. I provide information about the overall usage as well as the combinations of assessments and practical exams that candidates complete.
Decision Classification Consistency and Accuracy for Boom Truck Form 1
This is a quick analysis of Form 1 for the Boom Truck Mobile Crane Certification assessment. I conducted a non-parametric decision classification consistency and accuracy analysis on the response data (1s and 0s) using Lathrop and Cheng's (2014) method. Alternative methods would be Lee or Rudner. These are IRT-based approaches. https://onlinelibrary.wiley.com/doi/10.1111/jedm.12048
Assessment Usage by Hour, Day, and Month
This report provides the average number of assessment submissions by hour, day, and month. The data span 2021, 2022, and 2023. Thus, the averages are across all years.
Pipefitter JTA Information
This is JTA information from O*NET for Pipefitters and Plumbers.
Moving Average Convergence/Divergence (MACD) Graph for Assessment Sales 2018-2023
An MACD is a graph of oscillating moving averages combined with an overall moving average that represents a trend. The oscillations represent whether a short-term exponential moving average is higher or lower than a longer-term exponential moving average. An exponential moving average weights later values more than earlier values. The moving average leans towards what is happening now. If the MACD is positive, then that means that the short-term moving average is increasing compared to the longer-term moving average. If the MACD is negative, then that means the short-term moving average is decreasing compared to the longer-term moving average. If the MACD is near or essentially zero, then that means there is stability in the short-term and longer-term moving averages. The overall moving average (i.e., signal) is a representation of a long-term trend in the values. This moving average is also exponential.
