Teacher Guide to Surveys
Surveys are a popular method of research, particularly with the advent of the Internet and other communication technologies.
WHAT IS A SURVEY?
A survey is poll used to collect quantitative answers from a sample population. Surveys take two forms: interview and questionnaire. When the researcher asks the poll questions, it is called an "interview". In contrast, when the researcher hands out poll questions and collects written or otherwise recorded responses, it is referred to as a "questionnaire".
and Creating Line Graphs Lesson Series
Looks at the process of identifying the axis, plotting points, connecting points, and making sense of the outcome of data that is graphed. Includes estimating with line graphs and predicting outcomes based on past data. Provides plenty of guided and independent practice for creating and reading line graphs.

TYPES OF SURVEYS
Surveys may be of one of three different types:
- Cross-sectional surveys
If a survey is only taken once, or if the survey is administered several times with a different sample group each time, it is called a cross-sectional survey.
- Longitudinal surveys
Longitudinal studies involve administering surveys to a group of participants and then administering the same survey after a specific period of time.
- Time-series surveys
Times-series are similar to longitudinal surveys in that both administer the same survey to the same sample population on different occasions, however a time-series survey can have variant periods of time between survey administrations, whereas longitudinal surveys cannot.
and Creating Pie Charts and Graphs
This series walks students through the process of identifying a pie graph legend and key, creating pie graphs, and understanding the reason for graphing this data. Includes estimating with pie charts and predicting outcomes based on past data.

WHY USE SURVEYS?
Surveys have several advantages. They are easy to administer, very flexible (they can ask any question), standardized (the exact same question can be asked and a specific set of possible responses can be provided, making statistical testing easier), and less expensive than many other forms of research.
Pre-made rubrics specifically designed for use with math classes and assignments. Rubrics to help assess all types of math problems and projects.
WHAT ARE THE DISADVANTAGES OF SURVEYS?
However, surveys have several disadvantages. Most notably, surveys suffer from response rate. At the onset of a survey, a specific population is sampled. If only a portion of that sample respond to the survey, the results may be skewed. In addition, the participant's responses may be affected by variants that do not contribute to the question - for example, someone may respond differently based on mood, word perception (both knowing the definition accurately and any feelings that are elicited by a particular word), honesty (survey respondents may subconsciously try to give answers that please the researcher), etc.
HOW ARE SURVEYS USED?
The primary purpose of a survey is to gather data about a population, be it demographic or preference-related. Surveys are used by governments, businesses, marketing firms, schools, nonprofit organizations, and researchers, among others, to find out information about a population.
Examples of surveys include: TV ratings, election polls, market research, the US Census, customer satisfaction, brand awareness, etc.
and Creating Bar Graphs
A great self guided series of lessons for students on bar graphs. It walks students through the process of identifying the axis, plotting points, connecting points, and making sense of the outcome of data that is graphed. This series works students through a process to transition to line graphs very quickly. Includes vertical and horizontal bar graphs. Provides plenty of guided and independent practice for creating and reading bar graphs.
