question 110

Multiple Choice

Write the best-fit linear model for the data.
-A study was conducted to compare the average time spent in the lab each week versus course grade for computer students. The results are recorded in the table below. Find a linear function that approximates a student's course grade
As a function of the number of hours spent in lab. $\begin{array}{cc}\text { Number of hours spent in labrade (percent) } \\\hline 10 & 96 \\11 & 51 \\16 & 62 \\9 & 58 \\7 & 89 \\15 & 81 \\16 & 46 \\10 & 51\end{array}$

• A) \(y = 1.86 + 88.6 x\)
• B) \(y = 88.6 - 1.86 x\)
• C) \(y = 44.3 + 0.930 x\)
• D) \(\mathrm { y } = 0.930 + 44.3 \mathrm { x }\)

Definitions:

Multiple-Baseline Designs

Multiple-baseline designs are experimental methods used to demonstrate the effect of an intervention across different settings, behaviors, or individuals by introducing the intervention at different times.

Internal Validity

The extent to which a study can demonstrate that a causal relationship exists between the variables tested, free from the influence of extraneous variables.

Intervention Phases

Different stages or segments in a research study or clinical trial where specific interventions or treatments are applied.

Intensive Single-Subject Designs

Research designs focusing on detailed examination and analysis of a single subject or case, often used in clinical or experimental settings.
