# 4th Grade - Collect Data For A Survey

 Grade Level: 4th Skill: Graphs and Charts Topic: Collect Data for a Survey Goal: Formulate survey questions; systematically collect and represent data on a number line; and coordinate graphs, tables, and charts. Skill Description: Understand how to develop survey questions and how to record and organize the data using tables, charts, and graphs (i.e. bar graphs, line plots, stem and leaf plots, tally charts, etc.).

## Building Blocks/Prerequisites

### Sample Problems

(1)

Use the tally chart to fill in the frequency table:

 Month Votes January \\\ February \\\\ \ March \\ April \\\\ May \\\\ \\\ June \ July \\ August \ September \ October \\\\ \\\ November \\ December \

 Month Frequency Cumulative Frequency January (3) □ □ ( 3) February (6) □ □ (9) March (2) □ □ (11) April (4) □ □ (15) May (8) □ □ (23) June (1) □ □ (24) July (2) □ □ (26) August (1) □ □ (27) September (1) □ □ (28) October (8) □ □ (36) November (2) □ □ (38) December (1) □ □ (39)
(2)

Use the cumulative frequency to determine the frequency:

How many people applied for the job?

 Day Frequency (Number of Applicants) Cumulative Frequency Monday □ (10) 10 Tuesday □ (7) 17 Wednesday □ (6) 23 Thursday □ (8) 31

(3)

Transfer the data to the line plot:

What is the scale for the graph below? ________ (0-50)

What is the interval? ____ (10)

### Learning Tips

(1)

Math vocabulary

Survey- a method of gathering information by asking questions

Frequency- the number of times an event or a response occurs

Cumulative frequency- the total amount of frequencies recorded

Range- the difference between the greatest and the least numbers in a set of data

Outlier- a value separated from the rest of the data

Scale- series of numbers placed a fixed distances on a graph

Interval- the difference between any two numbers on the scale of a graph

(2)

Tally Chart

A tally chart is used to show how often something happens. The grouping of the lines in 5s allows the person to determine the amount by looking at the data quickly.

Example:

 Color Blue Green Two-tone Hazel Brown Tally \\\\ \\\ \\ \\\\ \ \\\\ \\

You can easily determine the results of the survey.

Have your child practice making a tally chart with something that interests him/her. Such as, watch television and make a tally chart of how many times they show a commercial advertising for toys.

(3)

Types of charts and graphs

Tally Chart- a chart used to show how often something occurs (using tally marks)

 Color Blue Green Two-tone Hazel Brown Tally \\\\ \\\ \\ \\\\ \ \\\\ \\

Frequency Table- a table that uses numbers to record data about how often something happens

 Color Blue Green Two-tone Hazel Brown Frequency 4 3 2 6 7 Cumulative Frequency 4 7 9 15 22

Line Plot- A graph that shows the frequency of data along a number line

x x

x x x x

x x x x x

x x x x x x

--׀--------׀--------׀--------׀--------׀--------׀--------׀--------׀--------׀--------׀---

0 1 2 3 4 5 6

Stem & Leaf Plot- A table that shows groups of data arranged by place value

• Group the data by the tens digits

• Order the tens digits in a column from least to greatest to form the stems

• Write each ones digit to the right of the stem (from least to greatest)

Bar Graph- a way to show information that uses bars to stand for data

(4)

How to formulate survey questions

• Make the questions clear, precise and simple

• Keep the questions specific (not allowing for a wide range of answers)

• Ask each person the question only once

• Use tally marks to record each person’s response

Practice devising survey questions to make sure your child id following the correct format to use the survey questions and get the results desired. They can call family and friends to practice asking the survey questions and recoding the data.

(5)

Scale and intervals

The scale is the series of numbers placed at fix distances (similar to the range). The scale of the graph above is 0 – 8.

The interval is the difference between the numbers on the graph. The interval for the graph above is 2.

Cut out different types of graphs and have your child identify the scale and intervals for each one. They can compare and see how they change for different data being graphed. Thereafter, have them make a bar graph and determine their scale and intervals for their data.

### Extra Help Problems
