24 Questions
What is the primary focus of cognitive neuroscience?
The study of the brain's production of thoughts and behaviors
What is the primary principle behind functional magnetic resonance imaging (fMRI)?
Tracking brain activity by measuring changes in blood flow
What is the primary application of Positron Emission Tomography (PET) scans?
Analyzing brain metabolism and blood flow
What is a key advantage of Electroencephalography (EEG)?
Capability to study rapid brain reactions
What is the primary difference between Magnetoencephalography (MEG) and EEG?
MEG measures magnetic fields, while EEG measures brain electricity
What do both EEG and MEG have in common?
They both detect neural activity
What is the main purpose of a scatter plot?
To show the relationship between two quantitative variables
What type of variables are typically represented on a scatter plot?
Quantitative and quantitative
What is the term for a two-dimensional statistic?
Application C
What is represented on the x-axis of a scatter plot?
The response of individual ω to the variable X
What is the term for the variable on the y-axis of a scatter plot?
Second marginal statistic
What is the purpose of a contingency table?
To classify individuals into groups based on two categorical variables
What is the objective when a scatter plot exhibits a non-linear shape?
To seek a functional relationship between the variables
What represents the mean point with coordinates (X̄, Ȳ )?
The centroid
When can the linear correlation coefficient be used as a descriptive measure?
When the scatter plot indicates that the data points are scattered about a line
What should you watch for when using the linear correlation coefficient?
Outliers and influential observations
What can happen if outliers and influential observations are present in the data?
The sample means and sample standard deviations will be affected
What does a high correlation between two variables not necessarily imply?
A causal relationship between the variables
What does a scatter plot provide?
Immediate qualitative insights into the relationship between X and Y
What is the purpose of identifying the functional relationship between X and Y in a scatter plot?
To derive more quantitative insights into the relationship between X and Y
What is the term for the collection of points in an orthogonal coordinate system?
Scatter plot
What is the shape of the scatter plot when there is a strong linear correlation between X and Y?
Elongated around a line
What is the purpose of determining the equation of the regression line?
To determine the line that best fits the data
What is indicated by a highly dispersed scatter plot?
No apparent relationship between X and Y
