CORRECT ANSWERS GRADED A+
◍ ratio scale.
Answer: contains ordered values that are the same-contains absolute
meaningful zero-divided in meaningful way-zero is absolute zero and means
and absence of somethingex) cups of coffee- 2,4,6 or 0 which means no
coffee
◍ Each dot is placed....
Answer: above the score an the height of the frequency
◍ frequency tables.
Answer: displays the number of times (ex: frequency) a certain value
appears within the dataset in a table format
◍ descriptive statistics.
Answer: Involves analyses that provide a way to summarize and describe
data. Descriptive stats involve calculations such as the mean, median, mode,
standard deviation, variance and range of a set of scores
◍ What is one advantage of using a bar chart over a pie chart?.
Answer: Unlike pie charts, bar charts can be used to display the frequencies
for numerous categories and are, therefore, used more often to display the
results from studies with large datasets.
◍ Interval scale.
Answer: Variable dose not have ana absolute or meaningful zero
(temperature) it can have negative values
◍ outliers.
, Answer: extreme values in a dataset
◍ Discrete variables.
Answer: involves counting whole numbers (0, 1, 2, 3, ...)
◍ What are benefits to an independent measures study?.
Answer: Subjects are only in one group or the other, under a single
condition
◍ Independent samples t-tests are also known as ____..
Answer: independent measures t, student t, unrelated pairs t, unpaired t and
two sample t
◍ What kind of problem can arise in systematic sampling?.
Answer: someone finds out and avoids being the 5th person
◍ What is an ordinal scale of measure.
Answer: Used to describe qualitative variables, provide both categorical
information as well as rank by size or measure
◍ Which statistical method involves the use of sample data to make
predictions about the population in which the sample belongs?.
Answer: inferential statistics
◍ formula for sample SS.
Answer: SS= Σ(X-x̅)^2SS=sum of squaresΣ= sum upx̅= sample mean
X=score
◍ positively (right) skewed distribution mean, median and mode.
Answer: increasing order: mode-->median-->mean
◍ The range is calculated by....
Answer: subtracting the lowest value and the highest value in a dataset
◍ simple random sampling.
Answer: each member of the population has an equal chance of being
selected for the sample
◍ Quantitative variables can be either....
