Lesson 1.1
Statistics is the science, and art of collecting, _______, and drawing conclusions from data
What is Analyzing?
A circular graph used to represent data
What is a Pie chart?
This display method of showing quantitative data shows each data value as a dot above its location on a number line
What is a Dotplot
This part of a stemplot shows the leading digits of each data point, while the trailing digits are represented as leaves next to it
What is the Stem?
A _____, Shows each interval as a bar. The heights of the bars show the frequency or relative frequencies of values in each interval
What is a histogram?
Any attribute that can take different values for different individuals
What is a variable?
This type of chart is commonly used to display the frequency of different categories, where each category is represented by a bar.
In the context of a dot plot, this term is used to describe when one or more dots are significantly farther away from the other dots.
What is an outlier?
In a stemplot, if the data is evenly distributed across multiple stems, it suggests a more symmetrical distribution of data. This type of distribution is typically called?
What is a Uniform or symmetric distribution
What is Large?
This takes numerical values as a variable.
What is a quantitative variable
The process of finding the central relative angle
multiply the percent by 3.6
multiply the relative frequency by 360
In a dot plot, this is the term used to describe the vertical alignment of dots over the same number, indicating how many times a particular value occurs in the dataset.
What is Frequency?
This term refers to the individual data points represented as leaves in a stemplot, where each leaf corresponds to the trailing digits of the data value
What is the leaf?
In a histogram, these represent the ranges of data values that are grouped together. Each bar in the histogram represents one of these
What is an interval?
A Person, animal, or thing, described in a set of data
What is an Individual
Another name for a Two way frequency table
What is a Contingency Table.
In a dot plot, this term refers to how tightly or widely the data points are grouped around a central value
What is Variability or Spread
This term refers to a part of a stemplot where data values are organized into intervals, making it easier to spot the frequency of occurrences within each interval
What is a Class interval?
An alternate name for an interval
What is are Bins, Classes, Or buckets?
Ask questions, Collect data, Analyze data, and _____
What is interpret results
105 people were surveyed on favorite pets.
Dogs: 40 people
Cats: 35 people
Birds: 15 people
Fish: 10 people
Other: 5 people
What percent was birds?
The 3 step process of making a Dotplot by hand
What is
1.Draw and label the axis
2.Scale the axis
3.Plot the values
This feature of a stemplot helps organize the data by sorting it in ascending order, ensuring that the leaves (trailing digits) follow a consistent pattern
What is ordering the data
This is the term for the shape of the histogram when data is evenly distributed across all bins, with no distinct peak or trend
What is a Uniform Distribution?
