STAT 100 FINAL EXAM QUESTIONS WITH
ANSWERS LATEST UPDATE ALREADY
GRADED A+
A good statistical test is one with hypotheses that - correct
answer- produce non-overlapping probability distributions
A three way-table can be thought of as separate two-way tables
for each value of an additional ________ attribute - correct
answer- categorical
By picking one hypothesis in a statistical test, we are proving
that the other hypothesis is wrong. - correct answer-
false
Conditional relative frequencies are computed by dividing a
cell's frequency by the total of the - correct answer-
column
Determine whether two quantitative attributes are related by
considering the ______ value of the attribute on the _______
axis across different value of the attribute on the _________
axis. - correct answer- averages; vertical; horizontal
, Dividing the RMSE by the standard deviation of the response
variable creates a measure that can help you determine the
extent to which the model - correct answer- explains
variability in the response variable
Estimation error is the - correct answer- variability we
might expect around an estimate, since no estimate will be
perfect
Factors that are added to a model to adjust for potential
differences between a control and treatment group are called -
correct answer- covariates
How do statisticians and data scientists measure the association
between two rating scale or categorical attributes? - correct
answer- cramer's V
How do we quantify the difference in the location of two
distributions? - correct answer- effect size
How do we quantify the difference in the spread of two
distributions? - correct answer- ratio of SDs
