What are the benefits of using a histogram?
A histogram allows you to see the frequency distribution of a data set.
It offers an “at a glance” picture of a distribution pattern, charted in specific categories.
Histograms are one of the most frequently used methods for charting historical data..
What are the merits and demerits of histogram?
It helps to visualize the distribution of the data. Demerits are:1) Cannot read exact values because data is grouped into categories. 2) More difficult to compare two data sets. 3) Use only with continuous data.
What can you tell from a histogram?
A histogram shows bars representing numerical values by range of value. A bar chart shows categories, not numbers, with bars indicating the amount of each category. Histogram example: student’s ages, with a bar showing the number of students in each year.
What are the disadvantages of line graphs?
What Are the Disadvantages of A Line Graph?Plotting too many lines over the graph makes it cluttered and confusing to read.A wide range of data is challenging to plot over a line graph.They are only ideal for representing data made of total figures such as values of total rainfall in a month.
What are the advantages and disadvantages of bar chart?
Disadvantages: Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant.
What is a histogram and what is its purpose?
The purpose of a histogram (Chambers) is to graphically summarize the distribution of a univariate data set.
Why can a histogram be misleading?
The y-axis of a histogram shows how many observations are in each group, using counts or percentages. A histogram can be misleading if it has a deceptive scale and/or inappropriate starting and ending points on the y-axis. … It also makes the data set look smaller, if you don’t pay attention to what’s on the y-axis.
What are the disadvantages of using a histogram instead of a dot plot?
Disadvantages: Cannot read exact values because data is grouped into categories. More difficult to compare two data sets.
Why is a box plot better than a histogram?
A histogram is highly useful when wide variances exist among the observed frequencies for a particular data set. … This may lead one to assume the data is slightly skewed. However, when a box plot is used to graph the same data points, the chart indicates a perfect normal distribution.
