Introduction of frequency tables and histogram:
Frequency distribution represent a histogram is by means of the rectangles whose width represents class intervals and areas are directly proportional to the corresponding frequencies.” A frequency tables distribution applied for continuous quantitative data. The tabular collection of data is frequency distribution viewing how many interpretation lie above, or below the records. Histograms are helpful for interpreting tasks. The collections of groups of data called classes, and in the context of a histogram, they called as bins.
Constructing a Frequency Tables and Histogram:
Step 1 – Calculate the quantity of data
Step 2 - Review on a tally sheet
Step 3 – Calculate the range
Step 4 – Find the number of intervals
Step 5 - Calculate interval width
Step 6 - Identify interval of initial points
Step 7 - Calculate number of data in each interval
Step 8 - Plot the data
Step 9 - Add designation and tale
Explanation about Frequency Tables and Histogram:
A range of the Histogram equally separates all possible values in a data set of groups or classes. For each set of a 4-sided figure constructed with a base length, which is identical to the collection of values in that definite group, and an area directly proportional to the number of observations decreasing into that group.
The height of a four-sided figure, which is the same to the frequency density of the interval, i.e. the frequency, should split by the breadth of the interval. The total region of the histogram that exactly is identical to the number of data.I like to share this 6th grade math homework with you all through my article.
Frequency Tables:
Marks Frequency Cumulative frequency
0-5 3 3
5-10 9 12
10-15 18 30
15-20 26 56
20-25 30 86
25-30 38 124
i) Plot a points of coordinates such as (0,5),(5,10),(10,15),(15,20),(20,25),(25,30) and the related frequency can be identified and make the points.
ii) Take x -axis 1 cm = 5 unit, y -axis 1cm = 1 c.f.
iii) The number line represent by the horizontal axis, which displays the data in equal interval. The vertical axis represents the frequency of each bar.
