**A. What is a Histogram?**

A

*histogram*is "a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies."Refer definition from http://www.amathsdictionaryforkids.com/dictionary.html

**B. How do you Plot/Draw a Histogram?**

*Hint: Note the following*

.1 Data Range (its continuous not discrete)

.2 The x- and y- axes labels

.3 The interval of the histogram

**C. Shodor histogram activity**

Click here to manipulate a Histogram.

The Shodor histogram activity allows you to change the bin size for a data set and the impact on the curve.

**D. How do we analyse Histograms?**

Histograms allow us to analyze extremely large datasets by reducing them to a single graph

Bar chart is quantity vs type, while histogram is frequency vs intervals

ReplyDeleteHistogram about frequency while bar graph is about(most of the time) quantity

ReplyDeleteHistogram is about the frequency of somethin whereas a bra graph is about the quantity and that thing that you are comparing

ReplyDeleteHistogram measures the frequency of the data while the bar graph is the data.

ReplyDeleteHistogram measures how frequent the data happens while the bar graph is the data.

ReplyDeletea histogram is putting a frequency table into a form of a bar graph

ReplyDeleteThe difference is that with a histogram it measures a range while in a bar chart it measures specific amount and it displays it.

ReplyDeletehistograms measure in ranges while bar graph measure by the exact amount .

ReplyDeletehistogram have no spaces while bar graph is separated

In historgrams, there are frequencys and intervals. But in bar graphs the y-axis and the x-axis can be anything else.

ReplyDeleteA bar graph is to compare the frequency between objects while a histogram is to compare the frequency in a range in a data set.

ReplyDeleteA bar graph is to compare the variables in an easy to comprehend way, while a histogram will show the frequency in a set of data.

ReplyDeleteHistogram is for showing frequency in data and a bar graph is more useful for comparing variables.

ReplyDeleteA histogram show the times and intervals of something but the bar graph only shows the frequency between objects of comparison

ReplyDeleteHistogram is the frequency of data whereas a bar graph is the quantity and that you are comparing

ReplyDeleteHistograms show frequencies of a number while bar graphs compare the numbers itself.

ReplyDeletehistograms are for frequency while bar graphs are quantity
