What is the difference between cumulative relative frequency and relative frequency for each data value?

Short Answer

Expert verified

The ratio of the number of times a data value appears in a dataset is represented by relative frequency, whereas cumulative frequency is the sum of the relative frequencies.

Step by step solution

01

Content Introduction

Each frequency from a frequency distribution table is added to the sum of its predecessors to get the cumulative frequency. Because all frequencies have already been added to the previous total, the last value will always equal the total for all observations.

A relative frequency distribution is connected to a probability distribution, which is widely used in statistics, and illustrates the proportion of the total number of observations associated with each value or class of values.

02

Content Explanation

The ratio of the number of times a data value appears in a dataset is represented by relative frequency, whereas cumulative frequency is the sum of the relative frequencies.

Use the following information to answer the next nine exercises: The population parameters below describe the full-time equivalent number of students (FTES) each year at Lake Tahoe Community College from 1976鈥�1977 through 2004鈥�2005.

鈥� 渭 = 1000 FTES

鈥� median = 1,014 FTES

鈥� 蟽 = 474 FTES

鈥� first quartile = 528.5 FTES

鈥� n = 29 years

What additional information is needed to construct a box plot for the FTES for 2005-2006 through 2010-2011 and a box plot for the FTES for 1976-1977 through 2004-2005?

One hundred teachers attended a seminar on mathematical problem solving. The attitudes of a representative sample of 12of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The 12 change scores are as follows:

3;8;鈥�1;2;0;5;鈥�3;1;鈥�1;6;5;鈥�2

a. What is the mean change score?

b. What is the standard deviation for this population?

c. What is the median change score?

d. Find the change score that is 2.2 standard deviations below the mean.
