Data Handling

Home Data Handling Mean Median Mode Range Measures Of Central Tendency The beginning of statistics is to know the measures of central tendency and variability. At once, we will relate measure of center and variability over a range of data called the data distribution. These worksheets on mean, median, mode, range, and quartiles make you recognize the measure of center for a set of data. Let us discuss about each measure in detail: 1.Mean The average value of a set of numbers is called the mean. Add all the numbers to get a total and then divide the total by the number of entries. 2. Median The middle number of a sorted data is called the median (ascending or descending data sample). When the data sample has odd entries pick the middle value where half of the data lies below and above the middle value. When the data sample has even amount of numbers, you have two median numbers. Here just add these numbers and divide them by 2. 3. Mode The data that appears more often in a data set is the mode. This measure can have more than one value for a set of data. 4. Range The difference between the highest and lowest values in a data set is called the range. 5.Quartiles A quartile divides data into three points. They are lower quartile, median, and upper quartile to form four groups of the dataset. Lower quartile is also called as first quartile, second quartile as median and third quartile as upper quartile. The distance between the first quartile and the second quartile is called the interquartile range. Measures Of Central Tendency : Mean, Median, Mode and Range Teachers and parents love using these worksheets because they’re simple and effective. They support classroom lessons, homework, and review activities. Answer keys often come included, so checking work takes just a few minutes. As students progress, worksheets introduce larger data sets and mixed problems. This boosts their ability to analyze and compare different types of data. With each activity, students grow more confident and accurate. In conclusion, these worksheets provide clear, engaging practice for mastering key statistics skills. They turn complex concepts into simple steps. Add them to your learning routine, and help students become data-smart with ease.

Home Data Handling Pictographs Pictograph Worksheets Pictograph worksheets or picture graph worksheets in this section teach children to represent data using pictures or symbols. This graphical representation is much easier as the numerical data collected is represented using pictures. Worksheets without key for beginners, with key for grade 2 through grade 6, reading, interpretting, and drawing pictographs are all given for practice. Also, worksheets to represent data using Tally marks and Pictographs and matching data to the given pictographs are here for best understanding of both these topics. You can download all these free pictograph worksheets for abundant practice. Let us learn to represent the information on a picture graph The first step is to collect data. Example : Collect this data from your class. Suggest your friends 5 colors and ask them their favorite color. Lets consider 5 colors. Red, Blue, Green, Yellow and Orange. Make a small table to record this information. With the given information, you can easily make a pictograph. Consider the key as 2. Select a simple picture for the pictograph. 8 students like Red color. According to the key 2 students can be represented using a picture. How many 2’s are in 8. Its 8/2 = 4. Use 4 pictures.7 students like Blue color. Now divide 7 by 2. 7/2 = 3.5 or 3 1/2. So we will use 3 full pictures which represent 6 students and 1 half picture representing 1 student. Similarly you can represent pictures for Green, Yellow, and Orange. Observations  The most preferred color- Yellow  The least preferred color- Green  The total number of students surveyed= 8+ 7+ 4+ 12+ 10 = 41 Here we have prepared worksheets according to the Common core Standards. Worksheets can be used from grade 1 through grade 6. RELATED DATA HANDLING TOPICS  :   Tally marks Pictographs / Picture Graph Worksheets PDF
