Exercise 8.7 A social scientist wants to determine if a person’s height might be correlated with his or her sense of self-confidence. To explore this, the scientist recruits a group of participants and gathers two metrics: First the researcher administers the Acme Self-Confidence Instrument

(ASCI), a self-administered survey that produces a score between 0 and 50 (0 = very low self-confidence, 50 = very high self-confidence).

Second, the scientist measures the height (in inches) of each participant.

Data set: Ch 08 - Exercise 07A.sav Codebook Variable: height Definition: Height of participant (in inches)

Type: Continuous Variable: asci Definition: Acme Self-Confidence Instrument score Type: Continuous (0 = very low self-confidence, 50 = very high self-confidence)
