I am trying to find out how the willingness to pay is correlated to these two variables. Specify the cell range in the Input Y Range box as the dependent variable 3. Specify the cell range in the Input X Range box as the dependent variable or choose more than one column of variables if you are doing multiple regressions 4.

In the output, the Adjusted R Square measures the proportion of the variation in the dependent variable accounted for by the explanatory variables. If the adjusted R square is too low, the regression is not significant thus invalid.

The coefficient for product quality is 0. So we can infer that the product quality is highly positively correlated to the willingness to pay. Therefore, when making marketing decision, marketers should focus on the product quality according to this survey result.

In the survey, there are always some open questions which will allow respondents to fill in their own answers. It seems that there are no ways to do open questions analysis in Excel. However, I will introduce a very useful way to do the text analytics. Go to Wordle 2. Copy and paste the column of answers to the open questions.

Once for each question. Bigger font of a word indicates higher frequency of this word in the answers. How to Make a Pivot Table in Excel.

How to use the Histogram feature in Excel: Data Analysis Technique 2: How to measure central tendency and dispersion in Excel You can use the function wizard.

For example, you want to know the maximum value among all the values: But there is an easier way to compute all these in Excel: Data Analysis Technique 3: Comparing Means — Statistical Testing Heads up! The data is shown as below: How to use paired t-Test in Excel: Data Analysis Technique 4: See the example below: Click Insert — PivotTable 2. Highlight the range data 3. Here is what the column chart looks like: Correlations Correlations are used when you want to know about the relationship between two variables.

How to use correlations in Excel: Data Analysis Technique 6: Linear Regressions Regression is a more accurate way to test the relationship between the variables compared with correlations since it shows the goodness of fit Adjusted R Square and the statistical testing for the variables.

How to do regression analysis in Excel: Data Analysis Technique 7: Text Analytics In the survey, there are always some open questions which will allow respondents to fill in their own answers. How to do text analytics: Here are some useful resources for data analysis techniques: Aj 'Goch' Atalatti says: August 5, at 9: August 8, at November 25, at 4: November 25, at January 9, at January 9, at 1: July 15, at 9: September 22, at June 13, at August 3, at August 8, , 3 Comments.

June 7, , 1 Comment. In the table below, we explore this subcategory of participants more in-depth. From these results it may be inferred that the Boston program is not meeting the needs of its students of color. This result is masked when you report the average satisfaction level of all participants in the program is 2.

In addition to the basic methods described above there are a variety of more complicated analytical procedures that you can perform with your data. These types of analyses generally require computer software e. We provide basic descriptions of each method but encourage you to seek additional information e. For more information on quantitative data analysis, see the following sources: A correlation is a statistical calculation which describes the nature of the relationship between two variables i.

An important thing to remember when using correlations is that a correlation does not explain causation. A correlation merely indicates that a relationship or pattern exists, but it does not mean that one variable is the cause of the other. An analysis of variance ANOVA is used to determine whether the difference in means averages for two groups is statistically significant. For example, an analysis of variance will help you determine if the high school grades of those students who participated in the summer program are significantly different from the grades of students who did not participate in the program.

Regression is an extension of correlation and is used to determine whether one variable is a predictor of another variable. A regression can be used to determine how strong the relationship is between your intervention and your outcome variables. More importantly, a regression will tell you whether a variable e.

A variable can have a positive or negative influence, and the strength of the effect can be weak or strong. Like correlations, causation can not be inferred from regression. Quantitative Analysis in Evaluation Before you begin your analysis, you must identify the level of measurement associated with the quantitative data.

There are four levels of measurement: T-shirt size small, medium, large Example: Fahrenheit degrees Remember that ratios are meaningless for interval data. You cannot say, for example, that one day is twice as hot as another day. Items measured on a Likert scale — rank your satisfaction on scale of For example — 10 inches is twice as long as 5 inches This ratio hold true regardless of which scale the object is being measured in e. Below you will learn how about: Data Tabulation Descriptives Disaggregating the Data Moderate and Advanced Analytical Methods The first thing you should do with your data is tabulate your results for the different variables in your data set.

This will help you determine: The most common descriptives used are: Mean — the numerical average of scores for a particular variable Minimum and maximum values — the highest and lowest value for a particular variable Median — the numerical middle point or score that cuts the distribution in half for a particular variable Calculate by: Listing the scores in order and counting the number of scores If the number of scores is odd, the median is the number that splits the distribution If the number of scores is even, calculate the mean of the middle two scores Mode — the most common number score or value for a particular variable Depending on the level of measurement, you may not be able to run descriptives for all variables in your dataset.

Quantitative Data Analysis Techniques for Data-Driven Marketing Posted by Jiafeng Li on April 12, in Market Research 10 Comments Hard data means nothing to marketers without the proper tools to interpret and analyze that data.

In quantitative data analysis you are expected to turn raw numbers into meaningful data through the application of rational and critical thinking. Quantitative data analysis may include the calculation of frequencies of variables and differences between variables. A quantitative approach is usually.

Analyze Quantitative Data. Quantitative data analysis is helpful in evaluation because it provides quantifiable and easy to understand results. Quantitative data can be analyzed in a variety of different ways. Due to sample size restrictions, the types of quantitative methods at your disposal are limited. However, there are several. Quantitative Research Methods Quantitative means quantity which implies that there is something that can be counted. Quantitative research has been defined in many ways. It is the kind of research that involves the tallying, manipulation or systematic aggregation of quantities of data (Henning, ) John W. Creswell defined quantitative research .
