An excessive number of bytes sent compared to bytes received typically indicates an application-level issue or asymmetrical data flow, not necessarily poor AP placement.

A high signal-to-noise ratio (SNR) is a desirable condition, indicating a strong signal relative to background noise, which suggests good AP placement, not poor.

Excessive number of data retries is a symptom often caused by poor signal quality (like low RSSI/SNR), but low signal strength is the more direct and fundamental indicator of poor placement.

A low ratio signal strength indicator (RSSI or SNR) directly implies that the client is receiving a weak signal from the access point, which is a primary indicator of poor access point placement or excessive distance from the AP. Weak signal strength frequently leads to unreliable connections, slow speeds, and increased retransmissions.

Duplicate received packets can be caused by various network issues like improper spanning-tree configuration or faulty hardware, but it is not typically a direct result of poor AP placement.

'Poor statistics for the last 90 seconds' is a vague statement that does not specify which statistics are poor, making it unhelpful for diagnosing specific AP placement issues.
