Statistics Class 10 Maths (Chapter-14) NCERT Solutions (Part-1) | CBSE Class 10 Board Exams Prep
BYJU'S - Class 9 & 10・2 minutes read
The session focuses on solving NCERT statistics problems related to calculating means through direct and assumed methods, emphasizing the importance of organized data and accurate calculations for exercises like determining mean plant counts and daily wages. Additionally, students are encouraged to join a virtual quiz, participate in an English speaking program, and attend upcoming live sessions to enhance their understanding and application of statistical concepts.
Insights
- The session provides a focused approach to solving statistics questions from NCERT, specifically emphasizing the calculation of mean using direct and assumed methods, while excluding the step division method from the syllabus. This structured guidance helps students understand when to apply each method based on the size of their data sets, enhancing their problem-solving skills in statistics.
- Byju's offers a two-month English speaking program led by Cambridge certified teachers, aimed at boosting students' confidence and public speaking abilities. This initiative highlights the importance of communication skills alongside academic subjects, encouraging students to develop a well-rounded skill set that is crucial for their future endeavors.
- The session stresses the significance of accurately representing and calculating data in statistical analysis, including the conversion of discontinuous series into continuous ones and the creation of frequency distribution tables. This emphasis on precision not only aids in achieving higher marks in exams but also cultivates a deeper understanding of statistical concepts that students will encounter in real-world applications.

What is the assumed mean method?
The assumed mean method is a statistical technique used to estimate the mean of a dataset when the values are large or when the data is grouped. This method involves selecting a middle value, known as the assumed mean, around which the data is analyzed. By calculating deviations from this assumed mean and multiplying these deviations by their respective frequencies, one can derive a more accurate mean. This approach is particularly useful in scenarios where direct calculation of the mean is cumbersome due to the size of the data set. It simplifies the process by allowing for easier calculations and helps in minimizing errors, making it a preferred method in statistical analysis.
How do you calculate the mean?
Calculating the mean involves summing all the values in a dataset and then dividing that total by the number of values. For example, if you have a set of numbers representing the number of plants in several houses, you would first add all those numbers together to get a total. Then, you would divide that total by the number of houses to find the mean number of plants per house. In cases where the data is grouped, such as with frequency distributions, you may use methods like the direct mean or the assumed mean to facilitate the calculation. Each method has its own steps, but the core principle remains the same: total values divided by the count of values.
What is frequency distribution?
Frequency distribution is a statistical tool that organizes data into classes or intervals, showing how often each value or range of values occurs within a dataset. This method allows for a clearer understanding of the data by summarizing it in a table format, where each class is associated with a frequency count. For instance, if you were analyzing the daily pocket allowance of children, you would categorize the allowances into ranges (like $0-$5, $6-$10, etc.) and count how many children fall into each range. This visual representation helps in identifying patterns, trends, and outliers in the data, making it easier to analyze and interpret.
Why is practicing statistics important?
Practicing statistics is crucial for students as it enhances their understanding of mathematical concepts and improves their problem-solving skills. Mastery of statistical methods, such as calculating means and understanding frequency distributions, can lead to better performance in exams, as these topics are often heavily tested. Regular practice helps students avoid common mistakes and reinforces their ability to apply theoretical knowledge to practical situations. Furthermore, a solid grasp of statistics is essential not only for academic success but also for making informed decisions in real-life scenarios, such as interpreting data in various fields like economics, health, and social sciences.
What is a continuous series in statistics?
A continuous series in statistics refers to a data set where the values can take any number within a given range, allowing for fractional values. This type of series is characterized by the absence of gaps between the upper limit of one class and the lower limit of the next, creating a seamless flow of data. For example, if you are measuring heights, a continuous series would include all possible values within the range, such as 150.5 cm, 151.2 cm, etc. To convert a discontinuous series into a continuous one, adjustments are made to the class limits, ensuring that they align properly. Understanding continuous series is vital for accurate data representation and analysis in statistical studies.
