Standard deviation and variance for a population Average: 12 You are interested in the development of language in bilinguals. You are able to locate five families in the world with 18-month-old toddlers who are learning both Japanese and Amharic simultaneously. Given that these are the only families that fit this qualification, therefore, these five families are your study population. You test the children to see how many words they can speak in Japanese. The results are listed in the following table: Number of Words in Japanese 47 73 56 46 53 Toddler Calculate the mean for this population Type here to search
Explanation / Answer
The mean is the average of the numbers: a calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are.
Mean = (47 + 73 + 56 + 46 + 53)/5
Mean = 55
