Who is a optical code that represents data with bars of varying widths or heights?
An optical code that represents data with bars of varying widths or heights is known as a barcode. Barcodes are used to encode information such as product details, prices, and inventory data, allowing for quick and accurate scanning by barcode readers. Common types of barcodes include UPC, QR codes, and Code 39. They are widely used in retail, logistics, and various industries for tracking and managing products.
Measurements of the heights of various plants in an experiment are called?
Not sure data
What of graph is best for showing discrete data?
A bar graph is best for showing discrete data, as it effectively represents distinct categories with separate bars. Each bar's height corresponds to the frequency or value of that category, making it easy to compare different groups. Additionally, bar graphs can accommodate varying quantities and are visually intuitive for displaying categorical information.
What is the pictorial representation of data by using bars?
pictograph
What type of graph would be the best to show the heights of 30 fifth grade students?
A histogram would be the best type of graph to show the heights of 30 fifth-grade students. It allows for the visualization of the distribution of heights by grouping them into intervals (bins), making it easy to see patterns or trends. Alternatively, a box plot could also be useful for summarizing the data, showing the median, quartiles, and any outliers.

What is a way of showing the frequency of data using rectangular bars and the area they contain?
A bar graph

What do bars mean in the context of a graph or chart?
Bars in the context of a graph or chart represent data values or categories by using rectangular shapes of varying lengths or heights. Each bar typically corresponds to a specific data point or category, making it easier to visually compare and analyze the information presented.
How do you find the mode for a bar graph?
To find the mode from a bar graph, identify the bar with the highest frequency, which represents the value that occurs most often in the data set. The height of this bar indicates the mode. If multiple bars have the same highest frequency, the data set is multimodal, having more than one mode. If all bars have different heights, the data set has no mode.
What is a bar chart?
A bar chart is a graph in the form of boxes of different heights, with each box representing a different category of data, and each height representing a frequency.
What chart categorizes information?
A bar chart is a common type of chart that categorizes information by displaying data using horizontal or vertical bars of varying lengths. It is useful for comparing different categories of data and showing trends over time.
What is the difference between a chart and diagram?
The difference between graphs and charts is mainly in the way the data is compiled and the way it is represented. Graphs are usually focused on raw data and showing the trends and changes in that data over time.
What does numerical data mean?
Numerical Data means data consisting of numbers, not categories, such as the heights of students.
What are the vertical bars through the data points in this graph?
they are called error bars. It represents the amount of error associated with each data point
Which two commands in excel are data visualizations?
Color scales and data bars
