frequency normal distribution

The data represents the lengths (recorded to the nearest millimeter) of 40 leaves picked for an experiment. Form an appropriate frequency distribution. Find chi-square test value and check if the variable shown in the frequency distribution is normally..

Frequency Distribution - A teacher gave a test to a class of 26 students. The maximum mark is 5. The marks obtained by the pupils are: Such data as above is called ungrouped (or raw) data. We may arrange the marks in ascending or descending order. The data so represented is call..

The graph of a normal distribution will be ________. => It has no predictable shape or Skewed left or Skewed right or Symmetric..

Cumulative Frequency Distribution - 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 frequ..

Find the area under the normal distribution curve shown in the figure. => 15.59% or 9.01% or 84.41% or 94.41%..

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..
