The Data Cycle
Data that results in numbers or quantities
What is Numerical Data/Quantitative Data?
The method of collecting data that requires you to find someone else's data or research
The set of numbers that are labeled on the Y axis of a histogram
What are Frequencies?
What is a line plot/dot plot?
The process where we solve a real-world problem by collecting and analyzing data
What is the Data Cycle?
The first step in the Data cycle
What is formulating questions?
Data that cannot be counted or measured, but must fall into a group
What is Categorical data
The set of numbers that are always labeled on the X-Axis, and must be consecutive
What are intervals?
The two types of graphs where we cannot see individual data points
What are Histograms and Circle Graphs?
The group of people we are looking to investigate, in order so answer a question
What is the population?
The method used to complete the data cycle that requires you to watch the population
What is observation?
A question that is open ended, results in Numerical Data, and has multiple answers
What is a well formulated question?
The lowest and highest points of an interval (the X axis)
What are Boundaries
The three types of graphs best for analyzing numerical data
What are Histograms, Stem-and-leaf plots, and line plots?
A group of people selected from a larger population, in order to save time when gathering data
What is a sample?
When a graph such as a stem-and-leaf plot displays all of the individual data points
What is Discrete Numerical Data?
Our method of collecting data must be ____ and ____ in order to avoid harming participants
The missing intervals within this set:
(0-9, 10-19, _____, 30-39, 40-49, _____)
What are 20-29 and 50-59?
The three types of graphs best for analyzing Categorical data
What are Circle Graphs, Bar Graphs, and Dot Plots?
The process of selecting your sample from a larger population, ideally using a random method
What is sampling/random sampling?
The three characteristics of a well gathered sample
What are Randomly Selected, Big Enough, and Representative of the population
This method of acquiring data requires you to manipulate your population in order to collect data
What is an experiment?
A range of 30 ≤ x < 50 on a frequency table translates to this interval of numbers on a histogram
What is 30-49?
When creating a circle graph, it is ideal to limit yourself to this amount of categories
What is 10?
The conclusions we gather about a whole population when we gather data from a sample
Reasonable Assumptions
