Researchers prepared three groups of resumes to send to employment agencies and directly to employers. For one group, each resume was sent with a smiling picture (that is, a picture in which the candidate was smiling). In another group, each resume was sent with a non-smiling picture (that is, a picture in which the candidate was not smiling). In the third group, each resume was sent with no picture. The resumes in the groups were otherwise identical. The graph shows the callback rates for these three groups.
For both employers and employment agencies, the group with no pictures had the highest callback rate, though the difference between the group with the highest callback rate and the group with the next-highest callback rate was greater for employment agencies. Among the two groups of resumes with pictures that were sent to employment agencies, the group with smiling pictures had a slightly higher callback rate.
Based on the information given, use the drop-down menus to describe how to assign labels to the graph.
| Text Component | Literal Content | Simple Interpretation |
|---|---|---|
| Study Design | Researchers prepared three groups of resumes. | Three different resume types were created. |
| Group Differentiation | One group included a smiling picture, one included a non-smiling picture, and one had no picture. | The only variable was the presence and type of picture on the resume. |
| Control Variables | The resumes in the groups were otherwise identical. | All other resume features were held constant. |
| Recipients | Each group was sent to both employment agencies and directly to employers. | Resumes were sent via two different channels. |
| Measured Outcome | The graph shows the callback rates for these three groups. | Callback rate was the metric of interest. |
| Key Finding (No Photo) | For both employers and employment agencies, the group with no pictures had the highest callback rate. | Resumes without photos performed best overall. |
| Key Finding (Agencies) | The difference between the group with the highest callback rate and the next-highest was greater for employment agencies. | The gap in success was most pronounced for agencies. |
| Key Finding (Smiling) | Among resumes sent to employment agencies, the group with smiling pictures had a slightly higher callback rate. | With photos, smiling slightly helped at agencies compared to not smiling. |
| Chart Feature | What It Shows | Interpretation |
|---|---|---|
| Chart Type | Vertical bar chart with two groups of three bars each | Compares callback percentages across scenarios |
| Y-Axis | Percentage scale, \(\mathrm{0\%}\) to \(\mathrm{18\%}\) | Callback rate measure |
| X-Axis | Groups X, Y, and Z (left set and right set) | Same groups, two different recipient groups |
| Left Bar Set | X: \(\mathrm{9.2\%}\), Y: \(\mathrm{15.1\%}\), Z: \(\mathrm{15.7\%}\) | For first recipient group; Z is highest |
| Right Bar Set | X: \(\mathrm{13.9\%}\), Y: \(\mathrm{13.1\%}\), Z: \(\mathrm{16.9\%}\) | For second recipient group; Z is highest by more |
| Trend Observed | Z (no picture) outperforms both in both sets; X improves, Y falls in right set | No-picture resumes are most effective |
| Detail Observed | The advantage of Z is more pronounced in the right bar set (employment agencies) | Matches the textual findings |
The set of three bars on the right represents resumes sent [BLANK 1].
Group Z is the group that included [BLANK 2] pictures.
Blank 1 is determined by comparing the gap between the highest and next-highest callback rates in each set; a larger gap points to employment agencies. Blank 2 is answered by matching the highest callback rates to the description that the no-picture group had the highest rates; this is Group Z in both sets.
The two questions are independent. Determining the recipient type for each set of bars does not affect the identification of the no-picture group, and vice versa.
