We collected the data from a sample of 500 high school girls. Raw data is organized in table comprises the following frequency distribution.
BIRTH CONTROL | ||
Yes | No | Total |
438 | 62 | 500 |
The data is collected as raw data and the organized and summarized. The data is that of a true sample of representative population. The sampling method used is a true random sampling.
The dataset consists of 500 data distribution of high school girls. The data then depicts the number of girls on birth control and not on birth control.
We analyze the records on girls that are birth control and those who are not in birth control. We used a random sampling to reduce any bias in the sampling and thus a true representative sample was chosen. We also use a secondary research study as meta-analysis for our analysis for establishing any further support to our claims and validating them (Larkin, 2003).
The frequency distribution for the dataset is as follows;
Frequency | Relative frequency | Cumulative frequency | |
Girls on birth control | 438 | 0.876 | 87.6% |
Girls not on birth control | 62 | 0.124 | 12.4% |
500 | 1 | 1 |
We record the response yes & No as 0 -Yes, & 1 – No. We interpret the results of the frequency histogram as having a positive skewed. The shape of the distribution si that it has a left skewness.
The data is a categorical one breakdown with “Response” as Yes & No. We present it in form of Bar chart & Pie Chart;
The bar chart shows that the number of high school girls on birth control are higher than the high school girls not on birth control. The same is interpreted in the pie chart as percentages of high school girls on and not on birth control form out chosen data sample.
