Prefinals Evals (2019) by Keim Flashcards
Area between two points
Probability density function
Area to the left of a point
Commutive distribution function
Mode which is the point on the horizontal axis where curve is maximum
Mean
Curve is symmetric about a vertical axis through the
Mean
P stands for
Population proportion
Position of normal curve depends on
Mode
Shape of normal curve depends on
Population mean and SD
Type of question when asking for age
Fill in the blank questions
Investigator anticipate most likely responses to the questions
Close ended questions
Points above median will be FARTHER AWAY from the median than the points below it
Skwede to the right
Mode is 8, median is 10. What is unlikely the mean?
6
The rationale of this measure is to ensure an equal number of sample points
Mean
Median
Mode
Large number of observations in the higher values of the variable
Skewed to the left
Shape of the binomial probability distribution is determined by
Pop mean, pop variance
The normal curve approaches horizontal axis as it proceeds in either direction from mean
True
What response variables are mentioned in the study?
Breast cancer and colon cancer
What graphical presentation is best suited for distributions having a discrete basis of classification?
Vertical bar diagram
The principal strength of the sample is that is not sensitive to very large or very small values
Median
The most frequently occuring value among all the observations in a sample
Mode
The value near the center of a normally distributed data points
Mean
Median
Mode
To compare the variability of cholesterol measurement on a given person using autoanalyzer method and microenzymatic method (the two methods are both quantitative continous variables) it is besr to examine this measure:
Variance
Large data sets are best describe using these/this:
All of the above
What measurement of centrality can be used for a quantitative variable?
Mode
Amount of fat in a person’s diet
Independent variable
True of horizontal bar diagram
The magnitude for comparison is represented as bars whose lengths are proportionate to the values
Line diagram
Time series
Dot diagram
Correlation data for two quantitative variable
True of a frequency polygon
We are interested with measurement of area
What is a frequency polygon?
None of the above
For distribution of infants according to the number of illness episodes experienced during the calendar year, this presentation is appropriate
Vertical bar diagram
What presentation is/are appropriate for the distribution of children enrolled in the feeding program to sex?
All of the above
If a sample space contains a FINITE NUMBER of possibilities or an unending sequence with as many elements as there are whole numbers
Continuous sample space
If a sample space contains a INFINITE NUMBER of possibilities equal to the number of points on a line segment it is called a
Discrete sample space
