About "Analyzing histogram worksheet" Based on the above frequency table, let us make a histogram for the above data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. It differs from a bar graph, in the sense that a bar graph relates two variables, but a histogram relates only one.

Frequency Tables and Histograms Purpose: Participants will identify intervals for a data set, create a frequency table that describes the data in terms Frequency Table.Cumulative frequency is defined as a running total of frequencies.

The frequency of an element in a set refers to how many of that element there are in the set. Cumulative frequency can also defined as the sum of all previous frequencies up to the current point. The cumulative frequency is important when analyzing data, where the value of the cumulative frequency indicates the number of elements in the data set that lie below the current value.

The cumulative frequency is also useful when representing data using diagrams like histograms. The cumulative frequency is usually observed by constructing a cumulative frequency table.

The cumulative frequency table takes the form as in the example below. The set of data below shows the ages of participants in a certain summer camp. Draw a cumulative frequency table for the data. The cumulative frequency at a certain point is found by adding the frequency at the present point to the cumulative frequency of the previous point. The cumulative frequency for the first data point is the same as its frequency since there is no cumulative frequency before it.

A cumulative frequency graph, also known as an Ogive, is a curve showing the cumulative frequency for a given set of data. The cumulative frequency is plotted on the y-axis against the data which is on the x-axis for un-grouped data. When dealing with grouped data, the Ogive is formed by plotting the cumulative frequency against the upper boundary of the class.

An Ogive is used to study the growth rate of data as it shows the accumulation of frequency and hence its growth rate. A percentile is a certain percentage of a set of data. Given that the total number of elements in the data set is N. The term quartile is derived from the word quarter which means one fourth of something. Thus a quartile is a certain fourth of a data set.

When you arrange a date set increasing order from the lowest to the highest, then you divide this data into groups of four, you end up with quartiles. There are three quartiles that are studied in statistics. The First Quartile is equal to the data at the 25th percentile of the data. The first quartile can also be obtained using the Ogive whereby you section off the curve into four parts and then the data that lies on the last quadrant is referred to as the first quartile.

This is the equivalent to the data value at the half way point of all the data and is also equal to the the data value at the 50th percentile. The Second Quartile can similarly be obtained from an Ogive by sectioning off the curve into four and the data that lies at the second quadrant mark is then referred to as the second data. In other words, all the data at the half way line on the cumulative frequency curve is the second quartile.

The second quartile is also equal to the median. This is the equivalent of the the data at the 75th percentile. The different quartiles can be calculated using the same method as with the median. The first quartile can be calculated by first arranging the data in an ordered list, then finding then dividing the data into two groups. If the total number of elements in the data set is odd, you exclude the median the element in the middle.

After this you only look at the lower half of the data and then find the median for this new subset of data using the method for finding median described in the section on averages. The second quartile is the same as the median and can thus be found using the same methods for finding median described in the section on averages.Join Newsletter News. Welcome to the statistics and probability page at Math-Drills.

This page includes Statistics worksheets including collecting and organizing data, measures of central tendency mean, median, mode and range and probability. Students spend their lives collecting, organizing, and analyzing data, so why not teach them a few skills to help them on their way.

Data management is probably best done on authentic tasks that will engage students in their own learning. They can collect their own data on topics that interest them. For example, have you ever wondered if everyone shares the same taste in music as you?

Perhaps a survey, a couple of graphs and a few analysis sentences will give you an idea. Statistics has applications in many different fields of study. Budding scientists, stock market brokers, marketing geniuses, and many other pursuits will involve managing data on a daily basis.

Teaching students critical thinking skills related to analyzing data they are presented will enable them to make crucial and informed decisions throughout their lives. Probability is a topic in math that crosses over to several other skills such as decimals, percents, multiplication, division, fractions, etc. Probability worksheets will help students to practice all of these skills with a chance of success!

Calculating the mean, median, mode and range are staples of the upper elementary math curriculum. Here you will find worksheets for practicing the calculation of mean, median, mode and range. In case you're not familiar with these concepts, here is how to calculate each one.

To calculate the mean, add all of the numbers in the set together and divide that sum by the number of numbers in the set.

### Frequency Table - Categorical Data

To calculate the median, first arrange the numbers in order, then locate the middle number. In sets where there are an even number of numbers, calculate the mean of the two middle numbers. To calculate the mode, look for numbers that repeat. If there is only one of each number, the set has no mode.

If there are doubles of two different numbers and there are more numbers in the set, the set has two modes. If there are triples of three different numbers and there are more numbers in the set, the set has three modes, and so on.

The range is calculated by subtracting the least number from the greatest number. Note that all of the measures of central tendency are included on each page, but you don't need to assign them all if you aren't working on them all. If you're only working on mean, only assign students to calculate the mean. In order to determine the median, it is necessary to have your numbers sorted. It is also helpful in determining the mode and range. To expedite the process, these worksheets include the lists of numbers already sorted.

Normally, data does not come in a sorted list, so these worksheets are a little more realistic. To find some of the statistics, it will be easier for students to put the numbers in order first.

Teaching students how to collect and organize data enables them to develop skills that will enable them to study topics in statistics with more confidence and deeper understanding.

Interpreting and analyzing data worksheets including worksheets with stem-and-leaf plots, line plots and various graph types. Answering questions about graphs and other data helps students build critical thinking skills.

The versions with no questions are intended for those who want to write their own questions and answers. Standard questions include determining the minimum, maximum, range, count, median, mode, and mean.

Reorder the classes with their related frequencies in an ascending order lowest number to highestwhich is the most common. The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class.

Class boundaries are the numbers used to separate classes. The size of the gap between classes is the difference between the upper class limit of one class and the lower class limit of the next class. In this case. The lower boundary of each class is calculated by subtracting half of the gap value from the class lower limit. On the other hand, the upper boundary of each class is calculated by adding half of the gap value to the class upper limit.

Simplify the lower and upper boundaries columns. Add the lower and upper class boundaries columns to the original table.

Toggle navigation. A frequency table, also called a frequency distribution, is the basis for creating many graphical displays. It is the initial summary of the raw data in which the data have been grouped for easier interpretation.

First, we need to understand the difference between categorical data also called qualitative and numerical data also called quantitative. Categorical data puts the data into non-numerical categories, such as color, gender, grade on an exam, or type.

The color of a car or the breed of a dog would be examples of categorical data. Numerical data, on the other hand, puts the data into numerical categories, such as age, price, height, or number. Some examples of numerical data are the heights of girls in a particular classroom or the number of children in a family.

We can create a frequency table for either categorical or numerical data. For categorical data, each category and its frequency are shown, as in this frequency table, which summarizes the highest degree held by executives in 40 large corporations: Frequency Table of Highest Degree Held by CEOs of 40 Large Corporations It's easy to see that, for example, 20 of the CEOs have an MBA, 7 have a bachelor's, and 4 have a PhD. Notice that in this example we have categorical data because "degree" is a category.

Also notice that because the data are categorical in nature, the categories could have been ordered differently. That is, the order in which the categories are presented in a frequency table does not matter. Sometimes, we might find it desirable to express the frequencies in terms of percentages, and this data can be also be displayed in the frequency table.

## Frequency Distribution

We first calculate the relative frequency for each category, and then we convert each relative frequency into a percentage. To calculate a relative frequency, divide each category frequency by the total.

The decimal 0. The basic frequency table can now be expanded to include columns for the relative frequencies and the percentages. The frequency table, including the addition of the relative frequency and percentages for each category, is a necessary first step for preparing many graphical displays of categorical data, including the pie chart and the bar chart.Descriptive vs.
