#### Mean Count **Ioa** Formula. **Time**-based **IOA** algorithms evaluate the correspondence between the synchronization data of two observers. These measures include (a) the **total duration** and (b) the average **duration** per event. Table 3 summarizes the strengths of both algorithms. As a common example of a **time**-based **IOA**, consider the hypothetical data flow. If you are preparing for the BCBA or BCaBA exam, you know **how** important understanding and calculating **IOA** data can be. Use this mock exam to get comfortable with all of the formulas you need to know and be able to implement them, easily! Gain confidence and practice your skills. Board Certified Behavior Analyst (BCBA) is a certification of graduate-level in behavior analysis. The BCBA certified professionals are the practitioners who work independently towards providing behavior-analytic services. But before reaching that level, you must clear the compulsory exam first. Here, this practice test has more than 150 questions of the same.

**Total**Float: The amount that a task can move without affecting the final project completion date.

**Total**Float = LF – EF.

**Total**Float = LS – ES. Both of these formulas produce the same result. Free Float: The amount that a task can move without affecting other tasks. Free Float = ES2 – EF1. In this method, the frequency of the target behavior is determined in each time interval. To determine the

**IOA**using this method, for each interval, the sum of all the percentages of

**IOA**is divided by the

**total**number of intervals. Verified Answer The following steps are used to document interobserver agreement for frequency-within-interval. The

**IOA**method is classified into five groups based on the types of data needed, i.e. time step model, market supply model, stocks-based model, population balance model and sales-stock-lifespan model [10]. The population balance model and sales-stock-lifespan model are further classified as the advanced
