Solving Problems with Graphs (Stem and leaf, dot plots, and frequency tables)

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

Front

What is a dot plot?

Back

A dot plot is a simple way to display data using dots above a number line, where each dot represents one occurrence of a value.

Front

What is a frequency table?

Back

A frequency table is a table that displays the number of times each value occurs in a dataset.

Front

How do you find the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

How do you find the range of a dataset?

Back

The range is found by subtracting the smallest value from the largest value in the dataset.

Front

What does it mean to analyze data?

Back

Analyzing data means examining and interpreting the data to draw conclusions or make decisions.

Front

What is the purpose of using graphs in data representation?

Back

Graphs help visualize data, making it easier to identify patterns, trends, and relationships.

Front

How can you determine the most common value in a frequency table?

Back

The most common value is the one with the highest frequency in the table.

Front

What is the difference between a dot plot and a stem-and-leaf plot?

Back

A dot plot shows individual data points with dots, while a stem-and-leaf plot organizes data into stems (leading digits) and leaves (trailing digits) to show distribution.

Front

What is a key feature of a frequency table?

Back

A key feature of a frequency table is that it summarizes data by showing how often each value occurs.
