Mom, has your child learned about data processing? If so, your little one needs to learn at home to be able to complete the assignments at school.
Data is a collection of information or data obtained from observations. To process data, we use measures of central tendency, also known as central tendency. Some types of central tendency include the mean, median, and mode.
The mean is the arithmetic average value of the data we have. The mean is calculated by dividing the sum of the data values by the number of data points.
Meanwhile, the median is the data in the middle. The median is obtained by first sorting the data from smallest to largest.
Then, the mode is the value or data that appears most frequently or has the greatest frequency. To understand this more deeply, we can work on the following practice questions.
