Interpret center, spread and relative position: retrieval: a separate sample with explanations after your response.
Paper packet. Every task here also exists on screen, where it is checked automatically; answers written on paper are not assessed by Nydus. When you are back at a device, enter your answers there.
Interpret center, spread and relative position: retrieval: attempt the descriptive statistics sample without worked examples. Use the target of each question to decide which information matters, and record your initial response before reading its explanation.
What is the mode of 2,3,3,5,5,5,8?
In a data set, 11 occurs 4 times, 12 occurs 7 times and 13 occurs 5 times. What is the mode?
The percentile rank is defined here as 100 times the fraction of observations strictly below a value. In 4,6,6,9,10, what is the percentile rank of 9?
A score has exactly 72 of 90 comparison scores strictly below it. Under the strictly-below definition, what is its percentile rank?
Review the descriptive statistics decisions in this quantitative modeling sample. Identify the particular restriction or evidence that changed your answer, and return to the corresponding worked lesson before trying a new case.
