100
a categorical measurement expressed not in terms of numbers, but rather by means of a natural language description
What is qualitative data
100
chart used to represent the whole group using a circle
What is a pie chart
100
a histogram with one peak
What is unimodal
100
graph that helps compare patterns of many graphs
What is boxplot or stem and leaf
100
you use this to compare things with completely different data
What is z-score
200
who what why where when and how
What is the 5 W's
200
a chart that displays the distribution of a categorical variable, showings counts for each category next to each other for comparison
What is a bar chart
200
data that stands off away from the body of the distribution
What is an outlier
200
graph that helps compare shape center and spread of the graph
What is histogram
200
subtract the means then divide the difference by the standard deviation.
What is the z score formula
300
data that can only take specific numeric values
What is discrete data
300
a bar that is treated as a whole and is divided into segments corresponding to the percentage in each group.
What is a segmented bar chart
300
three things should you always use to describe quantitative distribution
What is shape center and spread
300
you use this when you use data measured over time
What is timeplot
300
when you add or subtract a constant to each value
What is shifting the data
400
data that can take on any value (within a range)
What is continuous data
400
the principle saying that the area occupied by a part of the graph should correspond to the magnitude of the value its represent.
What is the area principle
400
you use it when there are values that are extraordinarily large or small
what is the median
400
when can you look into the future using data
What is never unless you have strong non statistical reasons.
400
the condition where you check if the data is unimodal and symmetric
What is nearly normal condition
500
type of data is the number of words in a book
What is discrete data
500
1.) make a picture 2.) make a picture 3.) make a picture
What is the three rules of data analysis
500
Q3-Q1
What is the IQR
500
applying a simple function to make skewed distribution more symmetric
What is transforming data
500
the percent of values that fall within one standard deviation of the mean in a normal model
What is 68%
