A large, immediate change in pattern is a clear indication of a treatment effect in a single-subject research data. This sudden change in behavior is known as a "jump" and is a strong indication that the manipulation of the independent variable has had an effect on the dependent variable. The other options (delay between phase change and behavior change, continuation of the same average level, gradual change in behavior) may also be observed in single-subject research, but they are not as strong of an indication of a treatment effect as a sudden change in pattern.
