Understanding Frequency Tables

The video tutorial explains how to create a frequency table from math test scores. It describes the table's structure, with one column for scores and another for frequency. The process involves tallying data values and summing them to determine frequency. The tutorial emphasizes the importance of organizing data and provides a step-by-step demonstration of tallying scores across rows and calculating their frequencies.

What are the two main components of a frequency table?

• Categories and intervals

• Scores and averages

• Scores and percentages

• Categories and frequency

What is the purpose of tally marks in a frequency table?

• To list categories

• To determine intervals

• To calculate averages

• To count occurrences of data values

When tallying data values, does it matter if you go down the column or across the rows?

• Yes, it must be down the column

• Yes, it depends on the data

• Yes, it must be across the rows

• No, it doesn't matter

How many times does the score 100 appear in the data list?

• Four times

• Five times

• Six times

• Seven times

What is the frequency of the score 30 in the data list?

• Two

• Three

• One

• Zero

What is the frequency of the score 80 in the data list?

• Five

• Six

• Four

• Three

What is the frequency of the score 90 in the data list?

• Seven

• Six

• Five

• Four

What is the frequency of the score 50 in the data list?

• Five

• Four

• Three

• Two

What is the frequency of the score 60 in the data list?

• One

• Two

• Three

• Four

Why is it important to cross off data values as you tally them?

• To help with calculations

• To ensure all values are included

• To make the table look neat

• To avoid counting them twice
