Definition A power of ten is 10 raised to a whole number. For example, 101 = 10; 102 = 100; 103 = 1000 and so on. A power of a ten has one followed by as many zeros as the power. For example, 102 is equal to one followed by two zeros, i.e., 100. Rule When a decimal number…

Introduction Decimal multiplication is done in a similar way as whole number multiplication. Rules for Decimal Multiplication Problem 1 Multiply 13.4 0.35 Solution Step 1: 13.4 0.35 We line up the digits and not the decimal points We now multiply the numbers by ignoring the decimal points and assuming as if they were whole numbers.…

Decimal multiplication is like whole number multiplication. Rules for Multiplication of a Decimal by a Whole Number Problem 1 Multiply 0.13 25 Solution Step 1: 0.13 25 Multiplying without decimal point 13 25 = 325 Step 2: The number of decimal places in 0.13 is two The number of decimal places in 25 is zero So…

Decimal multiplication is similar to whole number multiplication. Rules for Decimal Multiplication Problem 1 Multiply 0.07 2.3 Solution Step 1: 0.07 2.3 Multiplying without decimal points 7 23 = 161 Step 2: The number of decimal places in 0.07 is 2 The number of decimal places in 2.3 is 1 Step 3: So the product has…

Introduction We can find either of the three measures of center for a given data set. However, we find that one of the three is the best measure to describe the given data. Rules to find the best measure to describe data Example 1 Which is the best measure to describe set of data given…

Introduction Outliers are data points that dont fit the pattern of rest of the numbers. They are the extremely high or extremely low values in the data set. A simple way to find an outlier is to examine the numbers in the data set. We will see that most numbers are clustered around a range…

Introduction In this lesson we are given a data set. We find its mean and median. Then one of its data is changed. We then find the changed mean and changed median after one of the data has been changed. Example 1 Find new mean and new median of the data set if a data…

Introduction The median of data set is found as follows. The numbers of the data set are arranged in an increasing ordecreasing order. We look for the middle number in the data set and it is the median of the data set. If the number data are odd, there will be one middle number which will be…

Introduction In this lesson, we are given a data set. We are given a new mean of the data set and are required find a new data member which when added will yield the new mean of the changed data set. Rules to find new score that will yield a new given mean Example 1…
