Explanation Given information: Data Item Frequency 11 5 12 5 13 3 14 1 16 3 17 1 Formula use: Mean = ∑ f i x i ∑ f i Concept used: We will make a table which consists of column x i , f i and x i f i , we will calculate the values of x i f i by multiplying the value of x i with corresponding value of f i , here f i means the frequencies. After calculating the value for x i f i , we will sum it up and then divide it by sum of f i To determine (b) Tocalculatethemedian of the given frequency distribution Data Item Frequency 11 5 12 5 13 3 14 1 16 3 17 1 To determine (c) Tocalculatethemode of the given data Data Item Frequency 11 5 12 5 13 3 14 1 16 3 17 1

Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…
