The PQ&R Corporation has developed a collection of training materials and skills tests for activities that accurately represent the types of tasks performed by employees in a production environment. Before any instruction is given, each trainee is asked to perform the training battery-a series of tasks for which they are about to receive training. Immediately on completion of instruction, trainees are again asked to perform the training battery to assess the effectiveness of instruction. After performing the battery for the second time, the trainees become employees of PQ&R. On completion of their six-month introductory period of employment, trainees are required to perform the training battery a third time.
For each of the following statements about the scores in Session 1, Session 2, and Session 3, select Yes if the statement is supported by the information provided. Otherwise, select No.
For at least one trainee, the posttraining score was greater than 3 times the pretraining score.
The data for Session 1 exhibit a positive correlation between pretraining and posttraining scores.
For the three sessions, the range of pretraining scores is least for Session 2.

|
Summary: PQ&R Corporation uses a three-stage assessment system (before training, after training, and six months later) with the same "training battery" to measure how well their production training program works and whether skills are retained on the job.
| Information from Dataset | Analysis |
|---|---|
| "The scores range from 0 to 100 points corresponding to how well the trainee performed the tasks in the battery" |
|
| "The graphic consists of a unique trainee identifier (composed of his or her session number and a letter)" |
|
| "that trainee's pretraining and posttraining scores, and a plus sign (+) indicating that trainee's six-month score" |
|
| "The pretraining score is typically the lowest" |
|
| Example shown: Trainee 1a scores - Pretraining: 26, Posttraining: 72, Six-month: 94 |
|
Summary: Source B explains how individual trainee performance is displayed using a 0-100 scale across the three assessment points from Source A, with the example showing substantial improvement from pretraining (26) through posttraining (72) to six months (94).
| Information from Dataset | Analysis |
|---|---|
| "The results for the three training sessions conducted in the most recent calendar year" |
|
| "Each session had exactly eight trainees and no trainee was in more than one session" |
|
| "The results for each session are given twice—on the left in pretraining-score order and on the right in posttraining-score order" |

Chart Analysis:
Summary: Source C shows that across three training sessions of 8 people each, all 24 trainees improved their scores and remained employed through the six-month assessment, with the dual ordering revealing that initial skill levels don't predict final performance rankings.
The PQ&R Corporation training program uses a standardized three-stage assessment system (pretraining, posttraining, and six-month) to track skill development for production employees. Key insights from the complete dataset:
In Plain Terms: I need to evaluate whether three specific mathematical/statistical claims about the training scores are supported by the data shown in the charts.
Key Constraints:
Answer Type Needed: Multi-statement verification requiring numerical comparison and correlation assessment
Description: The analysis mentions 'Training produces large score improvements - roughly doubling or tripling from baseline' and 'Initial skill level doesn't determine final ranking', but I need specific score values from Source C charts to verify exact ratios and ranges.
Can Answer from Analysis Alone: Partially - Statement 1 can be inferred from 'tripling' mention, Statement 2 from 'ordering changes' observation, but Statement 3 requires visual data examination.
Description: Evaluating three statements about training score patterns across sessions
Hypothesis: Each statement makes a specific claim about score relationships that can be verified against the visual data
In Plain Terms: Statement 1: Did any trainee improve their score by more than 3x?
In Plain Terms: Statement 2: Do higher pretraining scores predict higher posttraining scores in Session 1?
In Plain Terms: Statement 3: Is Session 2's pretraining score range the smallest?
Description: Cross-verification of findings against visual data and analysis
Points:
For at least one trainee, the posttraining score was greater than 3 times the pretraining score.
The data for Session 1 exhibit a positive correlation between pretraining and posttraining scores.
For the three sessions, the range of pretraining scores is least for Session 2.
