cumulative frequency polygon

Identify the incorrect statement. I. The histogram is a graph that displays the data by using continuous vertical bars of various heights to represent the frequencies of classes. II. The frequency polygon is a graph that displays the data by using lines that connect po..

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interva..

Cumulative frequency is obtained by adding the frequency of a class interval and the frequencies of the preceding intervals upto that class interval. This is explained by an example below. The following frequency distribution table gives the marks o..

In a frequency distribution, the mid-value of each class is obtained. Then on the graph paper, the frequency is plotted against the corresponding mid-value. These points are joined by straight lines. These straight lines may be extended in both directions to meet the X - a..

The cumulative frequency for the distribution of the distance (in miles) that 20 randomly selected runners ran during a week is given in the ogive. Find the interquartile range for the data by constructing a box plot. => 18.5, Figure 2 or 11.2, Figure 2 or 23.5, Figure 1 or 12, ..

Which of the following statement(s) is/are true? I. On a pareto chart, the frequencies should be represented on the y - axis. II. In a frequency distribution, the number of classes should be between 5 and 20. III. The three types of frequency distributions are histogra..

Which of the following statement(s) is/are true? I. The other name for an ogive is a frequency polygon. II. The boundaries for the class limits 8.6 - 8.8 are 8.55 - 8.85. III. A Pareto chart can be used to show the relationship between the parts and the whole. => II only or I an..

The distance traveled (in thousands of kilometers) by female drivers in an year is as recorded. Distance traveled Number of females (Frequency) 2 0 4 4 6 7 8 18 10 24 12 27 14 14 16 6 Construct a frequency polygon and find the mean. => graph 2 and 14.69 or graph 2 and ..

The airborne speeds (in miles per hour) of 21 planes are shown. Identify the frequency polygon that represents the data. Speed (in miles per hour) Number of planes (Frequency) 366 - 386 4 387 - 407 2 408 - 428 3 429 - 449 2 450 - 470 1 471 - 491 2 492 - 512 3 513 - 533..
