Statistics Final Exam With Answers
2025
descriptive stats -(correct answer)methods for summarizing data inferential stats -(correct
answer)method of making decisions or predictions based on data obtained subjects -(correct
answer)entities measured in a study population -(correct answer)all subjects of interest
sample -(correct answer)subset of the population for whom we have data population
parameter -(correct answer)refers to the numeric summary of population sample statistic
-(correct answer)numerical summary of a sample taken from a population randomness
-(correct answer)each subject of the population has the same chance of being included in the
sample variability -(correct answer)The extent to which the scores in a data set tend to vary
from each other and from the mean. categorical -(correct answer)each observation belongs to
a type or a set quantitative -(correct answer)the observations are numerical values discrete
-(correct answer)possible values form a set of seperate numbers, have a finite set of values
discrete examples -(correct answer)# of pets, #of siblings continuous -(correct
answer)possible values form an interval, infinite set of values continuous examples -(correct
answer)time, age, weight categorical visual aide -(correct answer)pie chart, bar graph
quantitative visual aide -(correct answer)dot plot, stem and leaf plot, histogram histogram
-(correct answer)graph using vertical bars to portray the frequencies of outcomes outlier
-(correct answer)value falling far from the rest of the data mean -(correct answer)sum of
values/# of observations, not resistant median -(correct answer)the midpoint of observations,
resistant mode -(correct answer)most frequently occurring value, resistant resistant -(correct
answer)outliers have little effect on the values range -(correct answer)difference between the
minimum value and maximum value standard deviation -(correct answer)how each value
differs from the mean Empirical Rule -(correct answer)The rules gives the approximate % of
observations w/in 1 standard deviation (68%), 2 standard deviations (95%) and 3 standard
deviations (99.7%) of the mean when the histogram is well approx. by a normal curve quartiles
-(correct answer)Measures of a central tendency that divide a group of data into 4 subgroups
