For each question, tick the correct answer or answers.

Q1) The distance between two points representing the k-th and k’-th categories
is smaller the more the categories both contain the same individuals
is larger the more the categories are rare
the distance between two categories, both with many individuals in them, has to be large
the distance between two categories, both with few individuals in them, has to be large

Q2) A rare category
has larger inertia than a more common category
is found far from the center of gravity of the point cloud of categories
is twice as far from the center of the cloud as a category with twice as many individuals in it
has an inertia twice as large as a category with twice as many individuals in it

Q3) The inertia of the point cloud of categories
is equal to the sum of the inertia of each category of each variable
is equal to the inertia of the point cloud of individualsbr> is equal to K/J - 1

Q4) The simultaneous representation plot
gives an optimal representation of the point cloud of individuals
gives an optimal representation of the point cloud of categories
is such that if an individual is close to a category, it must be in that category
is such that an individual will be located on the side of the categories it is in
is such that a category is on the side of the individuals who are in it

Q5) In the survey, one variable corresponds to age, and is coded in terms of different age groups.
The points representing age groups 65-69 and 70-74 will be far apart because these categories have no individuals in common
The points for the age groups 65-69 and 70-74 are likely to be close together because individuals from these two age groups are likely to belong to similar categories of the other variables
The age group 70-74 is close to the Retired category, which is a category of the CSP variable, because all of these individuals are retired.
